Abstract :
These days, most microprocessor and microcontroller designs are based on a Reduced Instruction Set Computer (RISC) core, and many operations - such as discrete cosine transform (DCT), inverse DCT, discrete Fourier transform (DFT), and fast Fourier transform (FFT)--are performed by a digital signal processor (DSP) system. Here, the authors present the design of a RISC and DSP system that uses very high-density logic (VHDL) and a field-programmable gate array (FPGA). This RISC is a 20-bit processor.
