In Considering memory system performance, two measures of memory access are

of primary interest: the frequency of memory accesses for instructions versus data

and the frequency of memory reads versus writes. Using the average Bench-

mark350-1809 instruction mix information for MIPS in the table below, find these

quantities for the integer benchmark:

a. The percentage of all memory accesses that are for data.

b. The percentage of all memory accesses that are memory reads, if 60% of data transfers are loads.
