Simplified Instructional Computer
From Wikipedia, the free encyclopedia
The Simplified Instructional Computer is a hypothetical computer described in Leland Beck's book System Software. Most real microprocessors have a complex instruction set and many subtleties to increase efficiency. These can be a distraction for students that are studying the essential and universal aspects of a microprocessor that are common to different designs. The architecture uses 3 byte integers, 5 registers and can access 215=32768 bytes of memory.
SIC has two versions: a standard version, SIC, and an extended version, SIC/XE. The extended version has floating point numbers.
