In many operating systems, address 0 can only be accessed by a Question 4.5: In this exercise, we examine in detail how an instruction is executed in a single-cycle datapath. LCDs are specific to an item or service (procedure) and they define the specific diagnosis (illness or injury) for which the item or service is covered. Also assume that on a single processor a program requires the execution of 2.56E9 arithmetic instructions, 1.28E9 load/store instructions, and 256 million branch instructions. mov bx, 029D6h xor bx, 8181h, If a datapath supported only the register addressing mode.

Assuming there are no stalls or hazards, what is the utilization of the data memory? Suppose that we measured the code for a given program in two different compilers and obtained the following data: 4.3: What is the sign extend doing during cycles in which its output is not needed? If we only have one memory (for both instructions and data), there is a structural hazard every time we need to fetch an instruction in the same cycle in which another instruction accesses data. P.
