ABSTRACT:
A pair of In-Circuit-Emulator modules are embedded within a microprocessor to implement parts of an In-Circuit-Emulator system. A first In-Circuit-Emulator module, the In-Circuit-Emulator memory mapping module, maps specified physical addresses into a debug memory. The physical addresses mapped into the debug memory are set by programmable registers. The second In-Circuit-Emulator module, the In-Circuit-Emulator breakpoint module, allows the user to set conditions that cause the processor to recognize specific bus events. The In-Circuit-Emulator breakpoint module monitors an internal bus and an internal bus controller. The user can set specific bus event conditions by writing to a set of breakpoint registers in the breakpoint module.
