ABSTRACT:
A debug network on a multiprocessor array includes communication channels, a master controller, and one or more individual debug units in communication with one or more of the processors. The master controller solicits information from the debug units by sending messages along the communication channels. The debug units can control some aspects of the processors, and can simply report on other aspects. By using commands to invoke processor action, then accessing the result, interactive debugging of a multiprocessor array is possible.
