[9:15 am, 24/01/2022] Ahmed: a. Discuss the memory components shown in Figure 1 and their relationship between access time, memory cost, and capacity of the memory hierarchy in the Pentium processor. [9:15 am, 24/01/2022] Ahmed: b. Based on Figure 1, explain how L1 and L2 cache able to reduce the processor's access time to the main memory.

Access time: 1 nanosecond L1 I-Cache 32 KB 32B CPU L2 Cache 256 KB I Main memory 8 GB L1 D-Cache 32 KB 32B 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 Li cache into a cache for instructions (called the I-cache) and a cache for data (called the D-cache)
