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.
