A computing system as described in which individual instructions are executable
in parallel by processing pipelines, and instructions to be executed in parallel
by different pipelines are supplied to the pipelines simultaneously. The system
includes storage for storing an arbitrary number of the instructions to be executed.
The instructions to be executed are tagged with pipeline identification tags indicative
of the pipeline to which they should be dispatched. The pipeline identification
tags are supplied to a system which controls a crossbar switch, enabling the tags
to be used to control the switch and supply the appropriate instructions simultaneously
to the differing pipelines.
