Abstract :
This paper presents the second version of the multimedia fixed-point DSP (MDSP) chip for portable multimedia services 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 2-D video signal processing and 1-D signal processing. The MDSP chip has 73,095 gates, has been fabricated, and is running at 30 MHz
