A branch target cache or branch target instruction cache , the name used on ARM microprocessors, [38] is a specialized cache which holds the first few instructions at the destination of a taken branch.

This is used by low-powered processors which do not need a normal instruction cache because the memory system is capable of delivering instructions fast enough to satisfy the CPU without one.

However, this only applies to consecutive instructions in sequence; it still takes several cycles of latency to restart instruction fetch at a new address, causing a few cycles of pipeline bubble after a control transfer.

A branch target cache provides instructions for those few cycles avoiding a delay after most taken branches. This allows full-speed operation with a much smaller cache than a traditional full-time instruction cache.

Smart cache is a level 2 or level 3 caching method for multiple execution cores, developed by Intel. Smart Cache shares the actual cache memory between the cores of a multi-core processor.

In comparison to a dedicated per-core cache, the overall cache miss rate decreases when not all cores need equal parts of the cache space.

Consequently, a single core can use the full level 2 or level 3 cache, if the other cores are inactive.

Another issue is the fundamental tradeoff between cache latency and hit rate. Larger caches have better hit rates but longer latency.

To address this tradeoff, many computers use multiple levels of cache, with small fast caches backed up by larger, slower caches.

Multi-level caches generally operate by checking the fastest, level 1 L1 cache first; if it hits, the processor proceeds at high speed. If that smaller cache misses, the next fastest cache level 2 , L2 is checked, and so on, before accessing external memory.

As the latency difference between main memory and the fastest cache has become larger, some processors have begun to utilize as many as three levels of on-chip cache.

Price-sensitive designs used this to pull the entire cache hierarchy on-chip, but by the s some of the highest-performance designs returned to having large off-chip caches, which is often implemented in eDRAM and mounted on a multi-chip module , as a fourth cache level.

The benefits of L3 and L4 caches depend on the application's access patterns. Examples of products incorporating L3 and L4 caches include the following:.

Finally, at the other end of the memory hierarchy, the CPU register file itself can be considered the smallest, fastest cache in the system, with the special characteristic that it is scheduled in software—typically by a compiler, as it allocates registers to hold values retrieved from main memory for, as an example, loop nest optimization.

However, with register renaming most compiler register assignments are reallocated dynamically by hardware at runtime into a register bank, allowing the CPU to break false data dependencies and thus easing pipeline hazards.

Register files sometimes also have hierarchy: The Cray-1 circa had eight address "A" and eight scalar data "S" registers that were generally usable.

There was also a set of 64 address "B" and 64 scalar data "T" registers that took longer to access, but were faster than main memory. The "B" and "T" registers were provided because the Cray-1 did not have a data cache.

The Cray-1 did, however, have an instruction cache. When considering a chip with multiple cores , there is a question of whether the caches should be shared or local to each core.

Implementing shared cache inevitably introduces more wiring and complexity. But then, having one cache per chip , rather than core , greatly reduces the amount of space needed, and thus one can include a larger cache.

Typically, sharing the L1 cache is undesirable because the resulting increase in latency would make each core run considerably slower than a single-core chip.

However, for the highest-level cache, the last one called before accessing memory, having a global cache is desirable for several reasons, such as allowing a single core to use the whole cache, reducing data redundancy by making it possible for different processes or threads to share cached data, and reducing the complexity of utilized cache coherency protocols.

Shared highest-level cache, which is called before accessing memory, is usually referred to as the last level cache LLC. Additional techniques are used for increasing the level of parallelism when LLC is shared between multiple cores, including slicing it into multiple pieces which are addressing certain ranges of memory addresses, and can be accessed independently.

In a separate cache structure, instructions and data are cached separately, meaning that a cache line is used to cache either instructions or data, but not both; various benefits have been demonstrated with separate data and instruction translation lookaside buffers.

Multi-level caches introduce new design decisions. For instance, in some processors, all data in the L1 cache must also be somewhere in the L2 cache.

These caches are called strictly inclusive. Other processors like the AMD Athlon have exclusive caches: data is guaranteed to be in at most one of the L1 and L2 caches, never in both.

There is no universally accepted name for this intermediate policy; [45] [46] two common names are "non-exclusive" and "partially-inclusive".

The advantage of exclusive caches is that they store more data. This advantage is larger when the exclusive L1 cache is comparable to the L2 cache, and diminishes if the L2 cache is many times larger than the L1 cache.

When the L1 misses and the L2 hits on an access, the hitting cache line in the L2 is exchanged with a line in the L1. This exchange is quite a bit more work than just copying a line from L2 to L1, which is what an inclusive cache does.

One advantage of strictly inclusive caches is that when external devices or other processors in a multiprocessor system wish to remove a cache line from the processor, they need only have the processor check the L2 cache.

In cache hierarchies which do not enforce inclusion, the L1 cache must be checked as well. As a drawback, there is a correlation between the associativities of L1 and L2 caches: if the L2 cache does not have at least as many ways as all L1 caches together, the effective associativity of the L1 caches is restricted.

Another disadvantage of inclusive cache is that whenever there is an eviction in L2 cache, the possibly corresponding lines in L1 also have to get evicted in order to maintain inclusiveness.

This is quite a bit of work, and would result in a higher L1 miss rate. Another advantage of inclusive caches is that the larger cache can use larger cache lines, which reduces the size of the secondary cache tags.

Exclusive caches require both caches to have the same size cache lines, so that cache lines can be swapped on a L1 miss, L2 hit.

If the secondary cache is an order of magnitude larger than the primary, and the cache data is an order of magnitude larger than the cache tags, this tag area saved can be comparable to the incremental area needed to store the L1 cache data in the L2.

Each of these caches is specialized:. The K8 also has multiple-level caches. Both instruction and data caches, and the various TLBs, can fill from the large unified L2 cache.

This cache is exclusive to both the L1 instruction and data caches, which means that any 8-byte line can only be in one of the L1 instruction cache, the L1 data cache, or the L2 cache.

It is, however, possible for a line in the data cache to have a PTE which is also in one of the TLBs—the operating system is responsible for keeping the TLBs coherent by flushing portions of them when the page tables in memory are updated.

The K8 also caches information that is never stored in memory—prediction information. These caches are not shown in the above diagram.

As is usual for this class of CPU, the K8 has fairly complex branch prediction , with tables that help predict whether branches are taken and other tables which predict the targets of branches and jumps.

Some of this information is associated with instructions, in both the level 1 instruction cache and the unified secondary cache.

The K8 uses an interesting trick to store prediction information with instructions in the secondary cache. Lines in the secondary cache are protected from accidental data corruption e.

Since the parity code takes fewer bits than the ECC code, lines from the instruction cache have a few spare bits.

These bits are used to cache branch prediction information associated with those instructions. The net result is that the branch predictor has a larger effective history table, and so has better accuracy.

Other processors have other kinds of predictors e. These predictors are caches in that they store information that is costly to compute.

Some of the terminology used when discussing predictors is the same as that for caches one speaks of a hit in a branch predictor , but predictors are not generally thought of as part of the cache hierarchy.

The K8 keeps the instruction and data caches coherent in hardware, which means that a store into an instruction closely following the store instruction will change that following instruction.

Other processors, like those in the Alpha and MIPS family, have relied on software to keep the instruction cache coherent. Stores are not guaranteed to show up in the instruction stream until a program calls an operating system facility to ensure coherency.

In computer engineering, a tag RAM is used to specify which of the possible memory locations is currently stored in a CPU cache.

Higher associative caches usually employ content-addressable memory. Cache reads are the most common CPU operation that takes more than a single cycle.

Program execution time tends to be very sensitive to the latency of a level-1 data cache hit. A great deal of design effort, and often power and silicon area are expended making the caches as fast as possible.

The simplest cache is a virtually indexed direct-mapped cache. The virtual address is calculated with an adder, the relevant portion of the address extracted and used to index an SRAM, which returns the loaded data.

The data is byte aligned in a byte shifter, and from there is bypassed to the next operation. Later in the pipeline, but before the load instruction is retired, the tag for the loaded data must be read, and checked against the virtual address to make sure there was a cache hit.

On a miss, the cache is updated with the requested cache line and the pipeline is restarted. An associative cache is more complicated, because some form of tag must be read to determine which entry of the cache to select.

An N-way set-associative level-1 cache usually reads all N possible tags and N data in parallel, and then chooses the data associated with the matching tag.

Level-2 caches sometimes save power by reading the tags first, so that only one data element is read from the data SRAM.

The adjacent diagram is intended to clarify the manner in which the various fields of the address are used.

Address bit 31 is most significant, bit 0 is least significant. Although any function of virtual address bits 31 through 6 could be used to index the tag and data SRAMs, it is simplest to use the least significant bits.

The read path recurrence for such a cache looks very similar to the path above. Instead of tags, vhints are read, and matched against a subset of the virtual address.

Later on in the pipeline, the virtual address is translated into a physical address by the TLB, and the physical tag is read just one, as the vhint supplies which way of the cache to read.

Finally the physical address is compared to the physical tag to determine if a hit has occurred. See Sum addressed decoder.

The early history of cache technology is closely tied to the invention and use of virtual memory. The memory technologies would span semi-conductor, magnetic core, drum and disc.

Virtual memory seen and used by programs would be flat and caching would be used to fetch data and instructions into the fastest memory ahead of processor access.

Extensive studies were done to optimize the cache sizes. Optimal values were found to depend greatly on the programming language used with Algol needing the smallest and Fortran and Cobol needing the largest cache sizes.

In the early days of microcomputer technology, memory access was only slightly slower than register access. But since the s [51] the performance gap between processor and memory has been growing.

Microprocessors have advanced much faster than memory, especially in terms of their operating frequency , so memory became a performance bottleneck.

While it was technically possible to have all the main memory as fast as the CPU, a more economically viable path has been taken: use plenty of low-speed memory, but also introduce a small high-speed cache memory to alleviate the performance gap.

This provided an order of magnitude more capacity—for the same price—with only a slightly reduced combined performance. The first documented use of an instruction cache was on the CDC The , released in , has a "loop mode" which can be considered a tiny and special-case instruction cache that accelerates loops that consist of only two instructions.

The , released in , replaced that with a typical instruction cache of bytes, being the first 68k series processor to feature true on-chip cache memory.

The , released in , is basically a core with an additional byte data cache, an on-chip memory management unit MMU , a process shrink, and added burst mode for the caches.

The , released in , has split instruction and data caches of four kilobytes each. The early caches were external to the processor and typically located on the motherboard in the form of eight or nine DIP devices placed in sockets to enable the cache as an optional extra or upgrade feature.

This cache was termed Level 1 or L1 cache to differentiate it from the slower on-motherboard, or Level 2 L2 cache.

The popularity of on-motherboard cache continued through the Pentium MMX era but was made obsolete by the introduction of SDRAM and the growing disparity between bus clock rates and CPU clock rates, which caused on-motherboard cache to be only slightly faster than main memory.

The next development in cache implementation in the x86 microprocessors began with the Pentium Pro , which brought the secondary cache onto the same package as the microprocessor, clocked at the same frequency as the microprocessor.

The three-level caches were used again first with the introduction of multiple processor cores, where the L3 cache was added to the CPU die.

It became common for the total cache sizes to be increasingly larger in newer processor generations, and recently as of it is not uncommon to find Level 3 cache sizes of tens of megabytes.

Intel introduced a Level 4 on-package cache with the Haswell microarchitecture. Early cache designs focused entirely on the direct cost of cache and RAM and average execution speed.

More recent cache designs also consider energy efficiency , [57] fault tolerance, and other goals. There are several tools available to computer architects to help explore tradeoffs between the cache cycle time, energy, and area; the CACTI cache simulator [61] and the SimpleScalar instruction set simulator are two open-source options.

A multi-ported cache is a cache which can serve more than one request at a time. The benefit of this is that a pipelined processor may access memory from different phases in its pipeline.

Another benefit is that it allows the concept of super-scalar processors through different cache levels. From Wikipedia, the free encyclopedia.

Here we first send the request to the network using fetch , and only if it fails do we look for a response in the cache. This is also a good approach for resources that update frequently.

This approach will get content on screen as fast as possible, but still display up-to-date content once it arrives. This requires the page to make two requests: one to the cache, and one to the network.

We are sending a request to the network and the cache. The cache will most likely respond first and, if the network data has not already been received, we update the page with the data in the response.

When the network responds we update the page again with the latest information. Sometimes you can replace the current data when new data arrives for example, game leaderboard , but be careful not to hide or replace something the user may be interacting with.

For example, if you load a page of blog posts from the cache and then add new posts to the top of the page as they are fetched from the network, you might consider adjusting the scroll position so the user is uninterrupted.

This can be a good solution if your app layout is fairly linear. This technique is ideal for secondary imagery such as avatars, failed POST requests, "Unavailable while offline" page.

Network response errors do not throw an error in the fetch promise. Instead, fetch returns the response object containing the error code of the network error.

This means we handle network errors in a. Once a new service worker has installed and a previous version isn't being used, the new one activates, and you get an activate event.

Because the old version is out of the way, it's a good time to delete unused caches. During activation, other events such as fetch are put into a queue, so a long activation could potentially block page loads.

Keep your activation as lean as possible, only using it for things you couldn't do while the old version was active.

An origin can have multiple named Cache objects. To create a cache or open a connection to an existing cache we use the caches.

This returns a promise that resolves to the cache object. The Cache API comes with several methods that let us create and manipulate data in the cache.

These can be grouped into methods that either create, match, or delete data. There are three methods we can use to add data to the cache.

These are add , addAll , and put. In practice, we will call these methods on the cache object returned from caches. For example:. We call the add method on this object to add the file to that cache.

The key for that object will be the request, so we can retrieve this response object again later by this request. If any of the files fail to be added to the cache, the whole operation will fail and none of the files will be added.

This lets you manually insert the response object. Often, you will just want to fetch one or more requests and then add the result straight to your cache.

In such cases you are better off just using cache. There are a couple of methods to search for specific content in the cache: match and matchAll.

These can be called on the caches object to search through all of the existing caches, or on a specific cache returned from caches.

It returns undefined if no match is found. The first parameter is the request, and the second is an optional list of options to refine the search.

Lee November 8—12, General Electric. Another disadvantage of inclusive cache Teens in stockings porn that whenever there is an eviction in L2 cache, the possibly corresponding lines in L1 also have Ivy sex tape get evicted in order to maintain inclusiveness.
