Access time: 1 nanosecond LI I-Cache 32 KВ 32B L2 Main CPU Cache memory 256 KB 8 GB L1 D-Cache 32B 32 KВ Access time: 1 nanosecond Access time: 4 nanosecond Access time: 100 nanosecond Figure 1 Figure 1 illustrates a Pentium processor memory hierarchy. The Pentium processor features two caches, L1 and L2. Both caches use a 32-byte block size. L1 is located next to the CPU, whereas L2 is located between the processor and the main memory. Similar to other types of processors, the L1 cache is really two caches. The Pentium divides the L1 cache into a cache for instructions (called the I-cache) and a cache for data (called the D-cache).
