Abstract
A method of creating a prototype data processing system, by configuring a hardware development chip (HDC) according to user-defined settings, building user-defined logic adapted to function with the configured development chip, and allowing for the re-configuration of the HDC and user-defined logic after debugging. The HDC has several data processing macros including a processor core macro, a ROM emulation macro, a memory macro, and a bus macro. The macros may be configured by a configuration pin block which is connected to external configuration pins on the HDC. Customer logic is built using a field programmable gate array, which is interconnected with external ports of the HDC. The HDC and customer logic are verified using a debug port on the HDC, which is connected to a debug workstation. The invention allows a user to easily and quickly debug an application-specific integrated circuit (ASIC) design with a unique version of selected processor cores.
