FPGA的多处理器系统复杂电源管理研究

Research on Complex Power Management of Multiprocessor System Based on FPGA

多处理器控制系统对电源时序要求比较严格,而且各处理器芯片对供电电压的波动也十分敏感。多处理器控制系统在提供高性能的同时带来较大的功耗,而且不同芯片的负载也不完全相同。本文研究基于FPGA的复杂电源管理系统,能够满足多处理器控制系统严格的电源时序要求,芯片核心电压随负载动态微调以及对电源系统输入输出的过压、欠压和过流进行监视。

The multi-processor control system requires strict timing for power supply,and chip processors are also very sensitive to the fluctuation of power supply voltage.The multi-processor control system provides high performance with high power consumption,and the load of different chips are not the same.In the paper,a complex power management system based on FPGA is studied,which can satisfy the stringent power timing requirement of multiprocessor control system.It dynamically adjusts the core voltage of the chip with load,and monitors the input and output voltage of the power supply system whether there is over-current,under-voltage or overvoltage.
