Abstract

A microcomputer comprises memory (60) and a processor including a plurality of channels (70) to enable data transmission between concurrent processes. An inputting process may input data through one of a plurality of alternative input channels (70). Data transmission occurs when both processes are at corresponding stages in their programs. If an inputting process finds that no outputting process is yet ready on any of the alternative channels the inputting process may be descheduled and synchronisation achieved by special values located in locations (67) in a workspace (60) for the process.
