assembly - PC relative addressing in MIPS - Stack Overflow
Sep 7, 2021 · from what I have learnt about PC relative addressing in MIPs, we're supposed to count from PC + 4 to calculate the number of jumps needed in a beq or bne operation.
Trying to understand how jump instruction calculate the address when ...
The 13-bit immediate is used in a pc-relative addressing mode, so when the conditional branch is taken, the hardware computes: pc' := pc + signExtend(immediate12 ## 0) where pc' is the next pc, and ## …
Why does the ARM PC register point to the instruction after the next ...
Since most PC-relative addresses are calculated at link time, it's easier to have the assembler/linker compensate for that 2-instruction offset than to design all the logic to 'correct' the PC register. Of …
