Ibm instruction set
WebbThe IBM engineers realized that “logical structure (as seen by the programmer) and physical structure (as seen by the engineer) are quite different. Thus, each may see registers, counters, etc., that to the other are not at all real entities.” In more modern terms, we speak of the “Instruction Set Architecture”, or ISA, of a family of ... Webb4 dec. 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.
