Uniform Instruction Set Architecture
Machine Organization Accomplishment | 1964
IBM researcher: Fred Brooks
Where the work was done: IBM T.J. Watson Recent Center, IBM Poughkeepsie
What we accomplished: An instruction set, or instruction set architecture (ISA), is the part of the computer architecture related to programming, including the native data types, instructions, registers, addressing modes, memory architecture, interrupt and exception handling, and external I/O. Brooks' work allowed the same set of machine instructions to run on different implementations, e.g. from one generation of the machine to the next. ISA was first introduced in the IBM System 360.
