Abstract: PURPOSE: To attain a concentrical digital signal processing algorithm by using a conventionally available component element that operates at a conventional clock speed. CONSTITUTION: A single integrated circuit chip contains a CPU 200 which includes an execution device having an arithmetic and logic unit and an accumulator, a program counter, a memory, a clock generator, a timer, a bus interface, a chip selection/output device and an interrupt processor, a digital signal processor(DSP) 300 which includes an instruction set that executes the digital signal processing algorithm, an execution device that executes the multiplication and accumulation functions and an external interface, and a combination of an address bus 102 connected between the CPU 200 and the DSP 300, a data bus 104 connected between the CPU 200 and the DSP 300 and a static scheduler which statically executes the signal processing algorithm between the CPU 200 and the DSP 300.
