High-Performance and reliable processor design technology for military electronic system

With the development of the military electronic system information intelligence integration level, it needs to realize more and more kinds of tasks in more and more complex environment, which increases the requirements for High-Performance and High-reliable Processor. In order to meet the high performance application of processor in military electronic system, Dual-issue instruction execution technology, Branch prediction optimization technology, and TCM memory Management technology is used in this paper. For the high reliable using, lock-step instruction recovery technology is used in this paper for increasing the fault-tolerance of CPU. Also, ECC and redundant backup technology is used to improving the correction capability and reliability. Finally, an high-performance and reliable processor is fabricated on 90nm, which main frequency reaches 300 MHz, 2.0 D MIPS/MHz.
