Complex instruction set computers (CISC) supply relatively sophisticated functions as part of the instruction set. This gives the programmer a variety of powerful instructions with which to build applications programs and even more powerful software tools, such as assemblers and compilers. In this way, CISC processors seek to reduce the programmer’s coding responsibility, increase execution speeds, and minimize memory usage.
