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 lots of quirks built-in to increase efficiency. These quirks can be a distraction for students that are studying the essential and universal aspects of a microprocessor that are common to different designs. 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.
