| Abstract: | In this paper,we mainly introduced the application of digital signal processor(DSP)and CAN bus in the remote terminal control system.In order to improve the capability of processing signals and real-time response performance of the system,DSP and CPLD are adopted in the hardware,thus the integration degree and reliability are increased greatly.At the same time the ability that DSP visits the peripherals is strengthened a lot.In the software,design the way of modularization is used.To solve the simultaneous request of multitask to CPU and intersection problems,the interrupt resources of DSP are fully utilized,and the real-time property and running efficiency of the software is improved. |
