Abstract :
This paper presents a fixed-point multimedia DSP (MDSP) chip and instruction set for portable multimedia and its chip implementation. MDSP employs parallel processing techniques, such as SIMD, vector processing, and DSP schemes. MDSP can handle 8-, 16-, 32- or 40-bit data and can perform four MAC operations in parallel. In addition, MDSP can complete various vector operations in a cycle. With these features, MDSP can handle both 2D video signal processing and 1D signal processing. The second version of the MDSP chip with 73,095 gates, has been fabricated and is running at 30 MHz
