Data processing system with fully interconnected system architecture (FISA)

Abstract

A Fully Interconnected System Architecture (FISA) for an improved data processing system. The data processing system topology has a processor chip and external components to the processor chip, such as memory and input/output (I/O) and other processor chips. The processor chip is interconnected to the external components via a point-to-point bus topology controlled by an intra-chip integrated, distributed switch (IDS) controller. The IDS controller provides the chip with the functionality to provide a single bus to each external component and provides an overall total bandwidth greater than traditional topologies while reducing latencies between the processor and the external components. The design of the processor chip with the intra-chip IDS controller provides a pseudo “distributed switch” which may separately access distributed external components, such as memory and I/Os, etc.
