Abstract
An integrated circuitis provided with a data sourcein the form of a processor executing program instructions connected via a bus interconnectto a trace output device. The trace output deviceis memory mapped. Different memory addresses that are mapped to the trace output deviceare associated with different priority levels. Trace data written to at least one memory address has a first level of priority in which it is either accepted or the transfer is stalled until the data can be processed by the trace output device. Another level of priority associated with a different memory address is such that the data is always accepted but is discarded if the trace output devicedoes not have the ability to process, e.g. store that data at that time.
