Universal multi-bus breakpoint unit for a configurable system-on-chip

摘要

The present invention provides a hardware breakpoint unit for a multibus, processor-based, configurable circuit. The multi-bus breakpoint unit connects to and allows tracing of multiple busses and includes the ability to break on the occurrence of a pre-determined bus event on any one of the multiple busses. The multi-bus breakpoint unit can be connected to and programmed by a host debugging system via a port on the target chip.
