This thesis presents a novel Operating System (OS) that supports inter-processor communications. The OS developed addresses some real time control requirements and is optimized for embedded, distributed parallel processing system applications.

A review gives an overview of the key features of existing OS's and various message-passing mechanisms. Following the review, a novel OS was designed for a parallel processor StrongARM system. To further enhance the high level of abstraction for ease of parallel programming, two tools were developed to complement the OS. One of these tools is the Network Specifier, which allows the network mapping to be captured graphically, using GUI. A second tool, the NTU- Configurer, will generate routing headers automatically using Artificial Intelligence.

The OS design was captured in C, and minimal StrongARM assembly language using a top-down design methodology. The modules designed were tested, before being integrated to form the objective model. In the final form, various test codes were written to verify the functionality of the OS. Benchmarking and various measurement programs were performed to gauge the system overhead.

At a later stage, a project was undertaken in collaboration with Quantel to port an end user application. This was previously developed based on a multi-processor transputer system, using C and 3L libraries. It was adopted for a similar multiprocessor StrongARM platform to demonstrate the contributions of this thesis. The project was deemed successful after the porting of code to the new hardware, with only minimal modifications.

The thesis concludes by discussing key features of the system and comparisons are made to the state-of-the-art in parallel processing communication systems.
