Low Power Consumption Power Design and Implementation of High-speed Digital Signal Processing Platform

由于水声通信处理平台采用电池供电,为了尽可能降低系统耗电量,保障长时间可靠供电,提出了一种电源设计实现方案,着重介绍数字信号处理DSP与现场可编程门阵列FPGA这两个芯片的供电设计。结合实际应用环境,综合选择稳压器和开关电源混合系统,待机时采用掉电机制,实现低功耗、可扩充性的硬件平台。测试验证结果表明,设计的电源方案基本达到低功耗要求,可以应用到要求电源功耗较小的场景中。

As the platform uses battery,the paper introduces a power supply design program of high-speed signal processing platform in order to minimize the system power consumption and to achieve a reliable power supply for a long time,which mainly focus on DSP and FPGA chip power supply design.Combined with the actual application environment,a comprehensive selection of voltage regulator and switching power supply hybrid system,standby power-down mechanism to achieve low power consumption and scalability of the hardware platform.Finally,the platform power supply scheme is verified.Overall,the test results show that the power supply of the platform is low and effectively adapt to the power consumption of small occasions.
