Answer #1
  • Answer:-
  • ADD R1, R2, 8
  • The components which is used to generate a result during execution are:-
  • ​​1). Program counter PC, is a special-purpose register that is used by the processor to hold the address of the next instruction to be executed.
  • The PLA automatically updates the PC to point to the next instruction during the op-code decode cycle.
  • 3). Instruction memory The instruction is read from part of memory; load and store instructions then read or write data from another part of memory.
  • 4). Register file is the component that contains all the general purpose registers of the microprocessor. A few CPUs also place special registers such as the PC and the status register in the register file. Other CPUs keep them separate.
  • Those are the components which are used for us during this program execution.

    Consider a standard 5-stage MIPS pipeline of the type discussed during the class sessions: IF- ID-EX-M-WB. Assume that forwarding is not implemented and only the hazard detection and stall logic is implemented so that all data dependencies are handled by having the pipeline stall until the register fetch will result in the correct data being fetched. Furthermore, assume that the memory is written/updated in the first half of the clock cycle (i.e. on the rising edge of the clock) and...
