摘要

为了减少CPU 在进行速度信号测量时的资源占用率以及降低软件复杂度，设计某型车载设备时使用了FPGA（现场可编程门阵列，Field Programmable Gate Array）辅助CPU 进行速度及相关信息的测量。研究发现该方案既具有很好的精度，又极大地减轻了此过程的CPU 的占用率。

Abstract

In order to reduce CPU resource occupancy rate and the software complexity for velocity measuring, a FPGA(Field Programmable Gate Array) technology to measure velocity and related information was adopted as a supplement of CPU. It was pointed out that this method could increase the measuring resolution and reduce the CPU occupancy rate.
