Assume we hаve а clаssic 5-stage LC-2200 pipelined prоcessоr withоut data forwarding. This processor would need to add stalls to resolve RAW hazards. The hardware machinery does the following: In the ID/RR stage the instruction sets the B bit for its destination register (if any). In the WB stage, the instruction clears the B bit of its destination register (if any) after the register write is completed. In the ID/RR stage, if the instruction finds the B bit of any of its source operand registers set, it stalls (i.e., the instruction waits in the ID/RR stage and generates a NOP for the next stage until the B bit is cleared). Considering the following sequence of instructions, ADD R1, R2, R2ADD R5, R5, R5ADD R1, R3, R3ADD R4, R4, R1 Sean notices that this strategy leads to incorrect execution in the sequence of instructions above, so he modifies the hardware to do the following: When a [q1] dependency is encountered between an instruction in the ID/RR stage and a later stage, [q2] the instruction in the [q3] stage until the busy bit is [q4].
