The core is based on Harvard architecture with 16-bit instruction length and 8-bit data length. The performance of MCU has been improved greatly by introducing single-clock-cycle instructions, setting multiple high-speed working registers and replacing micro-program with direct logic block etc.
该MCU核采用哈佛结构、16位指令字长和8位数据字长,通过设计单周期指令、在内部设置多个快速寄存器及采用硬布线逻辑代替微程序控制的方法,加快了微处理器的速度,提高了指令的执行效率。
