Question

Given the following Omega network, whic allows 8 CPUs (P0 through P7) to access 8 memory modules (M0 trough M7):

a) Show how the following connections through the network are achieved (expalin how each switch must be set). Refer to the switches as 1A, 2B, etc.

i. P0 -> M2

ii. P4 -> M4

iii. P6 -> M3

b) Can these connectons occur simultaneously or do they conflict? Explain briefly.

c) List a processor-to-memory access that conflicts (is blocked) by the access P0 -> M2 tht is nt listed in part a).

d) List a procesor-to-memory access thatis not blocked byte access P0 -> M2 and is not listed in part a).

IF ANSWERED IN UNDER 1 HOUR, I WILL AWARD AN EXTRA 200 POINTS TO BEST ANSWER.

IF ANSWER IS CLEAR AND DONE WELL, I WILL AWARD AN EXTRA 100 POINTS TO BEST ANSWER.

a. No answer

b. No, there is a conflict between P0

-->M2 and P6 --> M3 in switch 3B.

Any access requiring switch 1A to be cross, 2A to be through, or 3B to be cross.

Any access NOT requiring 1A, 2A, or 3B, or those utilizing 1A through, 2A cross, or 3B

through.
