Abstract
This thesis presents the design and implementation of a transparent messaging protocol for distributed communication between processors. The processors are designed using dataflow architecture. The protocol ensures transparent asynchronous communication between distributed processes. The protocol is designed such that an application can run without change in virtually any kind of distributed configuration, where configuration is the number of controllers used in the system plus the processor allocation strategy used. It also enables an automated processor allocation strategy to transparently configure an application for any number of processor nodes without requiring any changes or recompilation. The protocol works well even for single-controller applications and for a pre-defined allocation of processors to controllers. The thesis further includes an analysis of the time required for one complete cycle of inter-processor communication.
