Fundamentals of memory

A collection of connected storage devices form the memory unit. It is a space to store data and instructions required for processing. Information is stored in a memory unit in the form of bits. There are two types of memory namely:

In a split L1 cache organization the I-cache size is 16-KB and the D-cache is 32-KB; the access time for both caches is 1 cycle. The miss rates are given in the table below. There is a 256KB second level cache (L2) that is a unified cache and has a miss rate given in the table. Please assume that miss penalty is 20 cycles to get data from L2 cache. There is a 4MB third level cache (L3) that has a latency of 42 cycles; its miss rate is 1.28%. 124 cycles are required to get data from main memory. A program executes 8.6×10° instructions; 32.8% of the executed instructions are data references (i.e. loads or stores).

A byte offset of 2 in an address means that each set in a multiway set associative (or in the directly mapped) cache has 4 bytes per set, per cache line. Keeping this in mind, answer the questions given the following details. A cache is organized as a 4 way set associative cache Each set's cache line consists of 4 words (meaning there are 16 bytes per line, for each set of the cache). Each set individually has one Valid bit, and one Dirty bit, for each line. The tag field of this cache is 8 bits wide. The address is 32 bits wide. Question 1g) If we have a write through cache coherency policy, will either of the above organizations make a difference in the amount of power used to do one write through operation (specifically above this cache layer, in the upper level memory structures to maintain coherency.
