英文摘要： This project focuses on the researches of architecture level design and evaluation for soft errors on multi core microprocessor. We will explore the feasibility of using the rich amount of resources in multi core microprocessor for soft error tolerance design. The goal of this project is to use the advantages brought by the development of microprocessor architecture to efficiently solve the threat of soft errors brought by the development of integrated circuit manufacture. This project will solve two key science problems in soft error tolerance design and evaluation on multi core microprocessors. One of the two problems is how to efficiently use the large amount of resources in multi core microprocessors in architecture level to achieve soft error tolerance with less or no extra overhead on area, performance and/or power. The three core redundant execution model will be proposed to use the redundant core resources, the hardware IO scrub technology to use the spare time resource, and a novel reset technology based on scan chain to use the existing hardware structure. The other of the two problems is how to quantitatively evaluate the reliability considering the overhead of area, performance and power. The novel quantitative evaluation metric and framework based on area, performance and power will be proposed in t
