Static and dynamic topological re-configurability in multi-microcomputer systems

摘要

This paper proposes a method of constructing multi-microcomputer systems which allows both static and dynamic topological re-configurability. The method uses a time-multiplexed shared bus which avoids bus contention altogether. Two systems are presented. In the dynamic, any number of micro-computers can be connected to the bus; the shared memory can be configured by software at run-time to allow the communication between any CEs, enabling interconnection topologies to develop dynamically. In the static, only two micro-computers are allowed to share a common memory, thus limiting topology modifications to physical changes of the connections between microcomputers.
