Assume we have a direct-mapped cache with 64 blocks and each block consists of 16 bytes, the cache is
initially empty. Consider the following MIPS code:
addi $t1, $zero, 1200 #1200 = 0100 1011 0000
addi $t2, $zero, 2400 #2400 = 1001 0110 0000
addi $t0, $zero, 10
loop:
beq $t0, $zero, exit
lw $t3, 0($t1)
lw $t4, 4($tl1)
lw $t5, 0($t2)
addi $t0, $t0, -1
j loop
exit:
What is the miss rate for the cache when executing the given code? Explain your answer.
