13. 8/5/2015\course\cpeg323-08F\Topic1.ppt13 Both hardware and software consist of hierarchical layers, with each lower layer hiding details from the level above. This principle of abstraction is the way both hardware designers and software designers cope with the complexity of computer systems. One key interface between the levels of abstraction is the instruction set architecture: the interface between the hardware and low-level software. This abstract interface enables many implementations of varying cost and performance to run identical software. John L. Hennessy David A. Patterson The Big Picture
