WebJul 8, 2024 · Total size of the L1 cache for all cores equals to the number of cores multiplied by the L1 cache size per core. Example: L1 Data cache = 32 KB per core L1 Instruction cache = 32 KB per core So the L1 cache size per core = 32 KB + 32 KB, which = 64 KB There are 4 cores reported, then the total size of L1 cache = 4 X 64 KB = 256 KB.

What is cache size and cache line size? - Stack Overflow
WebL1 Cache分为ICache(指令缓存)和DCache (数据缓存),指令缓存ICache通常是放在CPU核心的指令预取单远附近的,数据缓存DCache通常是放在CPU核心的load/store单元附近。 而L2 Cache是放在CPU pipeline之外的。 为什么不把L2 Cache也放在很近的地方呢? 由于Cache的容量越大,面积越大,相应的边长的就越长(假设是正方形的话),总有 … 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 (L1, L2, often L3, and rarely even L4), with different instruction-specific and data-specific caches at level 1. Th… gaither wiki
