The original design often featured a simple, limited set of commands, famously noted as having only 16 core instructions 2.2.4 .
Early concepts of primary storage (core memory), secondary storage, and addressing modes.
A simplified, theoretical computer model designed by Foster to teach students instruction sets and assembly-like programming without requiring a multimillion-dollar mainframe. Why Study Foster’s Architecture Today?
: Managing the "channels" that connect storage with external units, including "chained I/O" where channels can autonomously handle multiple data transfers. Hypothetical Time-Sharing Machine
This meant that programming Blue was an exercise in pure, low-level thinking. Without an “immediate mode” (loading a constant directly), programmers had to pre-store common values like 0 and 1 in memory. Complex tasks required the clever use of self-modifying code, where a program would rewrite its own instructions on the fly to loop or access data.
Caxton Foster is a renowned computer scientist and educator who has made significant contributions to the field of computer architecture. His book, "Computer Architecture," is widely regarded as a classic in the field and has been used as a textbook in many computer science courses.
The simplicity of Blue makes it a perfect starting point for those designing their first CPU. As one hardware guide noted, "Foster’s Blue computer has a pretty typical architecture of a minicomputer from the 1970s... Avoiding things like pipelines and multiple instruction issue lets you focus on the core principles".
