Labels are only so you can reference the line with a jump. The CPU itself will only see the machine code. The same is true of any comments in your code. They are only there in the assembler - this is then converted into machine code. You will need to jump over a line if you don't want it executing. Share. high street shirrell heath fareham so32 2jy

WebOct 18, 2016 · Branch Offset. MIPS branch offsets, like most processors, are relative to the address of the instruction after the branch. A branch with an immediate operand of zero is a no-op, it branches to the instruction after the branch. A branch with a sign extended immediate operand of -1 branches back to the branch.

"WebJun 2, 2024 · For example, in first-gen MIPS R2000, a classic 5-stage RISC, conditional branches only take half a cycle in the EX stage, and IF doesn't need the address until the 2nd half of a clock cycle, so the total branch latency is kept down to 1 cycle.MIPS hides that latency with a branch-delay slot: the instruction after a branch always executes, … " - Branch in mips
