Question
3. Caching
In this question, let's assume that we have a 16-bit system with a single level 6-way set associative
cache with 8 sets, and a cache block size of 64 bytes.
How many bits are needed for the setID and the tags? Draw the breakdown of the tag/index/byte-
in-block bits.
What is the total size of this cache?
For the following program, assume that an integer is 4 bytes.
int i; // Assume these variables are stored in the registers.
int a[65536]; // Assume that a = 0x1000
int b[65536]; // Assume that b = 0x8000000
for (i=0; i<1024; i++)
a[i* 8 ] = i;
for (i=0; i<1024; i++)
b[i * 8 ] = a[i * 8 ]++;
Let's asssume that the array is initialized to zero and that the variable i is already stored on the
register. What is my cache hit rate? Show your work.
