A 8-bit MCU design using a four-pipeline architecture

It is found that through improving the system architecture of PIC16C57's, the microcontroller's (MCU) execution efficiency can be improved apparently. Two-pipeline architecture in PIC16C57 is replaced by a four-pipeline architecture. Experiment results verify that the designed MCU is compatible functionally with PIC16C57, its execution efficiency is 4 times as high as that of PIC16C57, its system clock reaches above 60MHz.
