MULTIPLE PROJECT EMBEDDED ARCHITECTURE FOR DSP CORE BASED

PURPOSE: A multiprogram-mounted architecture based on a DSP(Digital Signal Processor) core is provided to manufacture a chip having various functions by embedding multiple programs in one chip and simply changing the external mode setup, and to prevent the degradation of the performance due to the increase of cycles. CONSTITUTION: The architecture comprises a DSP core(100) generating a program address and receiving various program data signals, a program ROM(200) divided into 2¬z parts, and a chip selection control unit(300) controlling the chip selecting signal of the program ROM. If the program address generated from the DSP core consists of K-bit, the program address is connected to the input address of the program ROM. Then, the addressing of each program ROM is performed. A mode and the program address are inputted to the chip selection control unit. The chip selecting signals of each program ROM are controlled. Thus, various program addressing modes are provided.
