Question: For debugging, it is useful to be able to detect when a particular value is written to a particular memory address. We want to add

For debugging, it is useful to be able to detect when a particular value is written to a particular memory address. We want to add two new registers, WADDR and WVAL. The processor should trigger an exception when the value equal to WVAL is about to be written to address WADDR. How would you change the pipeline to implement this? How would this SW instruction be handled by your modified datapath?

The remaining three problems in this exercise also refer to the following store instruction: SW b. SW a. R5,-40 (R15) R1,0 (R1) Store Instruction

SW b. SW a. R5,-40 (R15) R1,0 (R1) Store Instruction
