Abstract
An integrated circuit real-time data tracing apparatus for analyzing microprocessor based computer systems for monitoring, in real-time, parameters sufficient to define the load and store operations information that the embedded core controller may assert, and process information during events. Integral on this single chip apparatus is a data trace unit designed to access control, address, and data signal lines required to monitor the embedded core controller's activities; perform data tracing independent of instruction tracing; synchronize with an instruction trace stream; allow for selection of multiple ranges for data tracing; report lost events to a FIFO array; and, output strobe signals to give a cycle accurate indication of when an event has been captured.
