The Communication Interface Design of Fault Recorder Based on ARM and Linux
Zhu Heng-wei · Measurement & Control Technology · 2008
To solve some problems of hardware configure,cost and reliability based on the traditional microcomputer-based fault recorder,a scheme for the fault recorder which takes ARM and DSP as system hardware,Linux as system software is presented.DSP is used for high-speed data operation,and the ARM platform completes terminal control and communication.Then a simplified structure in software and hardware comes out.HPI technique is studied in detail in order to meet the demand of control and high-speed data communication between the two kernels.
