Using the first branch instruction in the given code as an example, describe the hazard detection logic

Question:

Using the first branch instruction in the given code as an example, describe the hazard detection logic needed to support branch execution in the ID stage as in Figure 4.62. Which type of hazard is this new logic supposed to detect?of Flash and $12, $2, $5 Clock 3 mumory Iw $4,50(57) Clock 4 nauction mary ------ boq $1,$3,7 Hard detection


This exercise is intended to help you understand the relationship between delay slots, control hazards, and branch execution in a pipelined processor. In this exercise, we assume that the following MIPS code is executed on a pipelined processor with a 5-stage pipeline, full forwarding, and a predict-taken branch predictor:a. b. Label1: LW R2,0 (R2) BEQ OR SW R2, RO, Label; Taken once, then not taken R2, R2, R3 R2,0 (R5) LW R2,0
