Abstract

This paper presents the design of 16M-byte addressing spaces in an MCU (micro-control unit) based on the structure of MCS-51. Both external data and program storage capacities are enlarged from 64K to 16M bytes without the increment of time-multiplexed address buses and the change of the whole instruction set. Thereby, a large number of data and programs with complex algorithms can be processed and run on this MCU. After the successful simulation at the front end, practical experiments made on a Nios development board verify that the design is correct. Furthermore, the design gains good effects in practical applications and enables the MCU to control an image processing system with much more than 64KB programs and tremendous data
