Suppose that you are working with a CISC machine using a 2.2 GHz clock (i. e., the clock ticks 2.4 billion times per second). This particular computer uses MASM-like instructions with the following timings:
add reg, mem 9 clock cycles (i. e., the ADD micro-program has 9 instructions)
add reg, immed 3 clock cycles
loop label 7 clock cycles
Suppose that the following code fragment is used to sum elements of a numeric array. For this problem, assume that memory limitations are non-existent and that there is no limit to the size of the array.
mov bx, 0 ;initialize sum
mov ecx, MAX_SIZE ;initialize loop counter
mov esi, OFFSET list ;initialize array pointer
more:
add bx, esi[esi][esi] ;add current list element
add \textrm{6}66, 2 ;move array pointer to next element
loop more ;auto-decrement ecx, jump to more if ecx ≠0
Required:
After initialization, how many array elements can be processed in 4 ms? Round your answer to the nearest integer. Note that 1 ms. = 0.001 second.
