Athlon was the first x86 processor with a 128 kB split level 1 cache ; a 2-way associative, later 16-way, cache separated into 2 × 64 kB for data and instructions ( Harvard architecture ).

This was done because the 250 nm manufacturing process was too large to allow for on-die cache while maintaining cost-effective die size.

This high-speed SDRAM cache was run at a divisor of the processor clock and was accessed via its own 64-bit bus, known as a " back-side bus " allowing the processor to both service system front side bus requests ( the rest of the system ) and cache accesses simultaneously verses the traditional approach of pushing everything through the front-side bus.

The major difference, however, was cache design.

With the older Athlon CPUs, the CPU caching was of an inclusive design where data from the L1 is duplicated in the L2 cache.

Because of Athlon's very large L1 cache and the exclusive design which turns the L2 cache into basically a " victim cache ", the need for high L2 performance and size was lessened.

Besides holding a large cache of ammunition and gunpowder, the Bastille had been known for holding political prisoners whose writings had displeased the royal government, and was thus a symbol of the absolutism of the monarchy.

It was also unique in that it was the only x86 design to incorporate a 256-byte Level 0 scratchpad cache.

Captain Kidd did bury a small cache of treasure on Gardiners Island in a spot known as Cherry Tree Field ; however, it was removed by Governor Bellomont and sent to England to be used as evidence against him.

The second, 21164 or EV5, was the first microprocessor to place a large secondary cache on chip.

On 14 July, the insurgents set their eyes on the large weapons and ammunition cache inside the Bastille fortress, which was also perceived to be a symbol of royal power.

* TFTH – ( Thanks For The Hunt or Hide or Hike ) It shares the same purpose as TFTC, but can also be used when the cache was not found.

* TN – ( Took Nothing ) no trade or traveling item was removed from the cache.

* LN – ( Left Nothing ) no trade or traveling item was added to the cache.

This was more than double the 36, 696 accounts that logged a cache on Leap Day 2008.

The design had two fully pipelined double precision multiply-add units, which could stream data from the 4 MB off-chip secondary cache.

They were therefore equipped with a 32KB L1 cache ( double that of pre-P55C Pentium CPUs ).

The chip was a heavily modified Pentium P54 architecture, made with 0. 6 micrometre technology and operating on 3. 3 volts, but with a half-wide data bus ( 32-bit ) and a larger 32 KB ( 16 KB + 16 KB ) L1 cache, double its P5-platform Pentium peers.

He reported that it could double the number of cache misses, but that its performance with double-ended queues was significantly better and should be retained for template libraries, in part because the gain in other cases from doing the sorts immediately was not great.

The main tradeoffs between these methods are that linear probing has the best cache performance but is most sensitive to clustering, while double hashing has poor cache performance but exhibits virtually no clustering ; quadratic probing falls in-between in both areas.

) Shaitan Singh escapes, stashes the gold cache somewhere, and double crosses the ACP.

This increases total cache size of the processor and effectively makes caching behave as if there is a very large L1 cache with a slower region ( the L2 ) and a very fast region ( the L1 ).

More efficient caches compute use frequency against the size of the stored contents, as well as the latencies and throughputs for both the cache and the backing store.

Another release of the 6x86, the 6x86MX, added MMX compatibility, introduced the EMMI instruction set, and quadrupled the primary cache size to 64 KB.

* Releasing a CPU on the same size die, but with a smaller CPU core, keeps the cost about the same but allows higher levels of integration within one VLSI chip ( additional cache, multiple CPUs, or other components ), improving performance and reducing overall system cost.

* Dhrystone's small code size may fit in the instruction cache of a modern CPU, so that instruction fetch performance is not rigorously tested.

Because the table is just 1024 bytes in size, it will fit into the cache of modern microprocessors

Modern computers face similar limiting factors: main memories are slow compared to the CPU and the fast cache memories employed to overcome this are limited in size.

To accommodate these features, the data cache was reduced in size to 8 KB.

This table contains specifications for certain SPARC processors: frequency ( megahertz ), architecture version, release year, number of threads ( threads per core multiplied by the number of cores ), fabrication process ( micrometers ), number of transistors ( millions ), die size ( square millimetres ), number of I / O pins, dissipated power ( watts ), voltage, and cache sizes — data, instruction, L2 and L3 ( kibibytes ).

Duron's biggest difference from Athlon was its reduction in cache size to 64 KB, in contrast to the 256 KB or even 512 KB of Athlon.

Consequently, the post-Slot-A K7-architecture was less sensitive to L2 cache size.

An algorithm designed to exploit the cache in this way is called cache-oblivious, because it does not contain the cache size ( s ) as an explicit parameter.

Moreover, D & C algorithms can be designed for important algorithms ( e. g., sorting, FFTs, and matrix multiplication ) to be optimal cache-oblivious algorithms – they use the cache in a provably optimal way, in an asymptotic sense, regardless of the cache size.

In order for a partial request to be satisfied at a fast speed from cache, Squid requires a full copy of the same object to already exist in its storage.

If the processor has an instruction cache, the original instruction may already have been copied into a prefetch input queue and the modification will not take effect.

It simply executes its old copy already loaded in the PIQ instead of the new and altered version of the code in its RAM and / or cache.

It is never worthwhile for simple variables and pointer fetches, because those already have the same cost of one data cache cycle per access.

And, for every file that is already cached and which we read from the cache ... do a write to the disk!

Subsequent pages will load faster because no style information will need to be downloaded – the CSS file will already be in the browser's cache.

The office's hosts will send packets addressed to IPs within this range directly, by resolving the destination IP address into a MAC address through an ARP sequence ( if not already known through the host's ARP cache ) and then enveloping the IP packet into a layer 2 ( MAC ) packet addressed to the destination host.

The CPU includes a cache controller which automates reading and writing from the cache, if the data is already in the cache it simply " appears ", whereas if it is not the processor is " stalled " while the cache controller reads it in.

This is where the cacher finds the travel bug and logs it as remaining in the cache it is already in and does not move it on.

Selkirk already wants to kill Jean-Paul for destroying a valuable weapons cache in Gotham Harbor.
