Branch Hazards - Peer Instruction for Computer Science Branch delay slot instruction (next instruction after a branch) is executed even. if the branch is ...

Schedule the instructions in the loop including the branch delay slot . Pipelined MIPS
CS252 S05 CMSC 411 - 5 (from Patterson) 9 Scheduling Branch Delay Slots • A is the best choice, fills delay slot & reduces instruction count (IC) • In B, the sub instruction may need to be copied, increasing IC • In B and C, must be okay to execute sub when branch fails add R1,R2,R3 if R2=0 then delay slot A. From before branch B. From branch target C.
CSE 141, S2'06 Jeff Brown Eliminating the Branch Stall • There’s no rule that says we have to see the effect of the branch immediately. Why not wait an extra instruction before branching? • The original SPARC and MIPS processors each used a single branch delay slot to … Having Fun with Branch Delay Slots – pagetable.com Abusing the load delay or branch delay on MIPS-I (and probably later chips too) is only safe if there is no way an interrupt can occur. When an interrupt occurs in a branch delay slot, the cpu subtracts 4 from the PC. However if you have a branch in a branch delay slot, then the CPU will subtract 4 from the address the second branch pointed at.

MIPS Delay Slot Instructions: TotalView Reference Guide (v6.3)
Delayed Branching in MIPS. It is assumed that the datapath neither stalls nor forwards. The problem gives two hints: it reminds us that branches and jumps are delayed and need their delay slots filled in and it hints at chaging the offset value in memory accesss instructions (lw,sw) when necessary. assembly - MIPS (PIC32): branch vs. branch likely ... MIPS (PIC32): branch vs. branch likely. If a branch or jump instruction is placed in the branch delay slot, the operation of both instructions is undefined. By convention, if an exception or interrupt prevents the completion of an instruction in the branch delay slot, the instruction stream is continued by re-executing the branch instruction. MIPS exception handling (Specifically branch delay slots ... the updating of the PC follows after the delay slot has been executed, until then it will point to the branch. there is no special handling during an exception except you have a register which says if you are in a delay slot or not. you`d need to emulate all instructions that can conditionally raise an exception in your handler (load/store ...
