Low-level-device programming with a high-level language
Siobhan Young · IEE Proceedings E Computers and Digital Techniques · 1980
This tutorial paper describes how device hardware may be programmed directly from a Pascal-like high-level language. The familiar data types of Pascal are extended to include information which specifies a mapping onto device hardware, and concurrent programming constructs are introduced as a natural environment for low-level I/O programming. Examples of interrupt-driven I/O are presented, and existing language designs are discussed.
