Abstract
A performance monitor is realized from programmable logic on the same integrated circuit as a processor. A user may use a programming and analysis tool to select a performance monitor soft core and to program it into the integrated circuit. The performance monitor is used to debug and/or monitor operation of the processor. After the debugging and/or performance monitoring, the portion of the programmable logic used to realize the performance monitor can be reconfigured and used to realize another portion of the user-specific circuit. Because the portion of the integrated circuit used to realize the performance monitor can be later used in the user-specific design, the cost of having to provide a no-longer-desired performance monitor in each integrated circuit used in the user's design is avoided. Because the performance monitor is realized from programmable logic, the performance monitor is more flexible than a conventional hardwired configurable performance monitor.
