【Abstract】 This paper discusses the necessity of bus correction in the protection based on the microprocessor and introduces the theory about the correction codes briefly.It is indicated that optimal minimum odd weight column codes can correct or detect effectively the errors of the bus data in the embedded system,and it can improve the reliability of the system.Finally,a realizing method of optimal minimumodd weight column codes based on PLD is brought forward.更多还原
