Abstract: By analyzing the application demand of the medical electronics, an MCU architecture named PKU-DSPII with application specific instruction set is proposed. Multilevel storage structures with direct memory access controller (DMAC) and abundant system control modules and peripheral interfaces are integrated in the MCU, which supports three booting modes including self-updating mode. PKU-DSPII is implemented with CSMC 0.18μm technology and LQFP package while the die area is 3.2 mm×3.2 mm and the measured power consumption is 96.9 mW at working frequency of 100 MHz.
