Elastic Pipeline Design of High Performance Micro-Controller YL8MCU for Signal Processing of Digital Home Appliances

With the growing complexity of the structure and function of the digital home appliance controllers, the higher requirements on the design of integrated circuits are expected. In view of the lower efficiency of the traditional large scale integrated circuit design, such as long design cycle, high investment and bad flexibility, therefore, the traditional design method is unable to meet the rapid product development. A design and its implementation scheme based on System-onProgrammable-Chip (SoPC) technologies with the Intellectual Property (IP) core parametric technology and elastic design method are proposed for the Micro-controller Unit (MCU) YL8MCU applied in digital home appliances. It makes used of Reduced Instruction Set Computer (RISC) framework and 5-stage pipeline technology for designing the instruction system and hardware structure so as to improve the speed of processing data and instructions. Finally the correctness and feasibility of its function is verified with the integrated verification, the IP function module verification based on coverage and the simulation test of the controlling flow for the washer. The results show that YL8MCU meets the requirements of digital home appliances and supports system integration on chip.
