Classify each of the below situations as either a structural hazard, control hazard, or a data hazard:

a. the memory shared by instruction fetches and data accesses in a von neumann memory architecture. this is
b. a conditional branch instruction in a risc processor. this is a __ .
c. an integer multiplier that takes two cycles to complete when all other arithmetic operations in a processor take one cycle. assume that there are sufficient register read and write ports to support all the necessary reads and writes per cycle. this is a
