A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.Most CPUs have a hierarchy of multiple cache levels …

Cache ([kæʃ], auch [kaʃ]) bezeichnet in der Informationstechnik einen schnellen Puffer speicher, der (wiederholte) Zugriffe auf ein langsames Hintergrundmedium oder aufwendige Neuberechnungen zu vermeiden hilft. Daten, die bereits einmal geladen oder generiert wurden, verbleiben im Cache, so dass sie bei späterem Bedarf schneller aus diesem abgerufen werden …

Small memories on or close to the CPU can operate faster than the much larger main memory.Most CPUs since the 1980s have used one or more caches, sometimes in cascaded levels; modern high-end embedded, desktop and server microprocessors may have as many as six types of cache (between levels and functions). Examples of caches with a specific function …

CPU clock rate: 1.00 GHz to 4.5 GHz: Cache; L1 cache: 64 KB per core: L2 cache: 256 KB per core: L3 cache: Up to 8 MB, share: L4 cache: 64 MB of eDRAM (on some models) ... However, CPU testing and binning allows for products with lower voltage/power at a particular frequency, or higher frequency within the same power limit.

A secure cryptoprocessor is a dedicated computer-on-a-chip or microprocessor for carrying out cryptographic operations, embedded in a packaging with multiple physical security measures, which give it a degree of tamper resistance.Unlike cryptographic processors that output decrypted data onto a bus in a secure environment, a secure cryptoprocessor does not output decrypted …

Xbox 360 took a different approach to hardware compared to its predecessor. The XCPU, named Xenon at Microsoft and "Waternoose" at IBM, is a custom triple-core 64-bit PowerPC-based design by IBM.The CPU emphasized high floating point performance through multiple FPU and SIMD vector processors in each core. The SIMD vector processor (VMX128) was modified for the …

The second generation Tegra SoC has a dual-core ARM Cortex-A9 CPU, an ultra low power (ULP) GeForce GPU, a 32-bit memory controller with either LPDDR2-600 or DDR2-667 memory, a 32KB/32KB L1 cache per core and a shared 1MB L2 cache. Tegra 2's Cortex A9 implementation does not include ARM's SIMD extension, NEON.There is a version of the Tegra 2 SoC …

As of 2020, the x86 architecture is used in most high end compute-intensive computers, including cloud computing, servers, workstations, and many less powerful computers, including personal computer desktops and laptops.The ARM architecture is used in most other product categories, especially high-volume battery powered mobile devices such as smartphones and tablet …

Nehalem / n ə ˈ h eɪ l əm / is the codename for Intel's 45 nm microarchitecture released in November 2008. It was used in the first-generation of the Intel Core i5 and i7 processors, and succeeds the older Core microarchitecture used on Core 2 processors. The term "Nehalem" comes from the Nehalem River.. Nehalem is built on 45 nm process, run at higher clock …

A central processing unit (CPU) is an important part of every computer. ... The L1 cache is the fastest (and most expensive per byte) cache and is "closest" to the CPU. The L2 cache is one step away and is slower than the L1 cache, etc. The L1 cache can often be viewed as a cache for the L2 cache, etc. Buses. Computer buses ...
