The syntax of the instructions is simple enough: SDIV Rd, Rn, Rm ; Rd = Rn / Rm The only real wrinkle you need to be aware of is the handling of division by zero. Again, the behavior varies by architecture.

WebDec 4, 2015 · The B instruction will branch. It jumps to another instruction, and there is no return expected. The Link Register (LR) is not touched. The BL instruction will branch, but also link. LR will be loaded with the address of the instruction after BL in memory, not the instruction executed after BL. WebBCC(short for "Branch if Carry is Clear") is the mnemonicfor a machine languageinstruction which branches, or "jumps", to the address specified if, and onlyif the carry flagis clear. If the carry flag is set when the CPU encounters a BCC instruction, the CPU will continue at the instruction following the BCC rather than taking the jump.
