摘要： 介绍一种用于混合信号处理器的嵌入式微控制器(MCU)系统。针对系统可重构的要求，采用将存储在片外EEPROM中的指令存取到片内指令SRAM中的方法，由MCU系统读取指令并执行所需要的操作。经过SMIC 0.18 µm CMOS混合信号工艺流片，芯片面积为 1.06 mm2，工作电源电压为1.8 V。测试结果表明，该系统能正确执行指令，产生符合SPI总线协议的数据对处理器进行配置，完成所需要的功能。

Abstract: An embedded Micro-Controller Unit(MCU) system for mixed-signal processor is introduced in this paper. According to the request of systems reconfiguration, all the instructions stored in the EEPROM off-chip are transferred into the SRAM on-chip and executed. The MCU system is fabricated in SMIC 0.18 µm mixed-signal CMOS process with an area of 1.06 mm2. It operates from 1.8 V power supply. Measurement results show that all of the instructions are executed correctly and it can be used to configure the function of the mixed-signal processor in a way compatible with SPI protocol.

Key words: embedded Micro-Controller Unit(MCU), reconfiguration, mixed-signal processor
