Consider a multiple-issue design. Suppose you have two execution pipelines, each capable of beginning execution of one instruction per cycle, and enough fetch/decode bandwidth in the front end so that it will not stall your execution. Assume results can be immediately forwarded from one execution unit to another, or to itself. Further assume that the only reason an execution pipeline would stall is to observe a true data dependence. Now how many cycles does the loop require? Latencies beyond single cycle
Memory LD +4
Memory SD +1
Integer ADD, SUB +0
Branches +1
ADDD +1
MULTD +5
DIVD +12
1 Loop: LD F2, 0(Rx)
2 IO: DIVD F8, F2, F0
3 I1: MULTD F2, F6, F2
4 I2: LD F4, 0(Ry)
5 I3: ADDD F4, F0, F4
6 I4: ADDD F10, F8, F2
7 I5: ADDI Rx, Rx, #8
8 I6: ADDI Ry, Ry, #8
9 I7: SD F4, 0(Ry)
10 I8: SUB R20, R4, Rx
11 I9: BNZ R20, Loop

Some of the items below indicate the steps required to move a slide to a different location in a presentation. select those steps and indicate the order in which they should be performed to move the slide. (for example, if an item describes what you do first, select 1.) included in the list are items that are not part of the process. for these items, select n/a, an abbreviation for not applicable. 1 — first 2 — second 3 — third 4 — fourth 5 — fifth 6 — sixth n/a — not applicable drag the slide to the desired place. enter the slide position desired. hold the mouse button down. select move from the tools menu. select the slide. switch to the notes view.
