Answer the following questions. A. A computer system has a main memory access time as 60ns. you as a computer organization expert has been asked to reduce the memory access time to 20ns by adding a suitable cache. Assume that the miss probability is 10%. What should be the fastness of cache (in terms of access time) for this requirement? B. Consider the instruction ADD R1, X, which adds the contents of location X from the contents of register R1, and places the result in R1. Show the micro-operations used during fetch and execution phase of the instruction.
