中文摘要	An application special processor, which uses embedded FLASH memory VLIW (very long instruction word) system to increase the chip's processing ability effectively, is introduced in this paper. The enhanced ALU, multiplier and multi-accumulator are integrated in the processor to realize micro controller and DSP in a single core with improved Harvard architecture. The memory indicating register and lever register group, which can simplify sub-program are used in the chip. The micro processor is fabricated by 0.25 mu m CMOS which area is 25 mm/sup 2/. The simulating result shows the chip working under 20 MHz has the same performance with 50 MI/s general purpose DSP and maintains the original coding quality. Many types of speech compression algorithm can be implemented and easily exploited on this processor, and they can achieve high security and low complexity.
