Integrated circuits for multi-tasking support in single or multiple processor networks

摘要

An integrated circuit ( 7 A) for multitasking support for processing unit ( 1 A) holds control variables for each task (or activity) to run on its associated processor ( 1 A) and identifies the next task that should run. The circuit ( 7 A) employs level-driven, clock free ripple logic and is configured as a two dimensional array of "tiles", each tile being composed of simple logic gates and performing a dedicated function. The circuit has particular application to asynchronous multiple processor networks.
