Abstract
A parallel processor is provided that includes integrated debugging capabilities. The processor includes a pipelined processing engine, having an array of processing element complex stages, and input and output header buffers. A debug system is provided that, when triggered, may put some or all of the processing element complexes into a debug mode of operation. When a complex is in debug mode, examination of internal stages of the component circuits of the complex may occur, in order to facilitate debugging of software and hardware errors that may occur during operation of the processor.
