MIPS Compare and Branch

Compare and Branch

beq rs, rt, offset if R[rs] == R[rt] then PC-relative branch

bne rs, rt, offset <>

Compare to zero and Branch

blez rs, offset if R[rs] <= 0 then PC-relative branch

bgtz rs, offset >

bltz rs, offset <

bgez rs, offset >=

bltzal rs, offset if R[rs] < 0 then branch and link (into R 31)

bgeal rs, offset >=

• Remaining set of compare and branch take two instructions

• Almost all comparisons are against zero!
