III.1 Instruction-set architecture: the hardware-software interface
Processor instructions de ne the most important hardware-software interface:
software programs use the processor instructions to carry out arbitrary data
processing, while electronic circuits interpret those instructions and perform
the requested actions in hardware. The instruction set abstracts away the details
of the hardware in much the same way as an object in a high-level programming
language hides its internal operation from its users.
There are potentially many ways to de ne this hardware-software interface
depending on how much ‘work’ the hardware is allowed to perform on its own
in order to carry out the actions required by an instruction. Different brands
of processors have different instruction sets because their designers have made
different…
