The core DSP is extended to a functional module extension, for example having extended memory and input/output circuitry, which extended module is mapped in the address base of the data storage of the core DSP, whereby an ASIC-expanded LSI may be wholly formed on a single semiconductor substrate in an efficient manner. That is, the data transfer, address signals and control signals usable within the core with respect to the core memory are equally applicable to the extended module, so that the core DSP does not have to be re-evaluated and the core instruction sets and software are equally applicable without debugging, when the core DSP is extended for a specific application by adding an extension module.
