故障录波器通信接口设计-Abstract: To s olve some p r oblems of hardware configure, cost and reliability based on the traditi onalmicr ocomputer2 based fault re2

corder, a scheme for the fault recorderwhich takesARM and DSP as system hardware,L inux as system soft ware is p resented . DSP is

used for high2s peed data operati on, and the ARM p latform comp letes terminal contr ol and communicati on . Then a si mp lified structure

in s oft ware and hardware comes out . HP I technique is studied in detail in order t o meet the demand of contr ol and high2s peed data

communicati on bet ween the t wo kernels .
