Question
Suppose that you are working with a CISC machine using a 1.6 GHz clock (i.e., the clock ticks 1.6 billion times per second). This particular computer uses MASM-like instructions with the following
timings:
ADD reg, mem
ADD reg, immed
LOOP _LabelName
; 8 clock cycles (i.e., the ADD micro-program has 8 instructions)
; 3 сlоck суcles
7 clock суcles
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
MOV
MOV
BX, 0
ЕСХ, МАХ_SIZE
ESI, OFFSET list ;initialize array pointer
;initialize sum
;initialize LOOP counter
_ProcessArray:
ADD
ADD
LOOP ProcessArray
ВХ, [ESI]
ESI, 2
;Add current list element
;Move array pointer to next element
;auto-decrement ECX, jump to more if ECX = 0
After initialization, how many array elements can be processed in 2.8 millisecond (ms)? Round your answer to the nearest integer. Note that 1 ms = 0.001 second.
