随着双电压体系结构和多处理器板的迅速普及,连简单的应用都可能需要几条处理器电压干线。由于每个处理器都有自己的加电和断电要求,电源干线排序和控制就变成一项复杂的任务。电源设计人员所面临的挑战就是要考虑每个处理器的定时和电压要求,并将这些要求吸纳到总系统中,以确保最终设计满足所有处理器的要求。给处理器供电不当,会导致种种问题,有
With the proliferation of dual-voltage architectures and multiprocessor boards, even a few simple applications may require several processor voltage rails. Because each processor has its own power-up and power-down requirements, power rail sequencing and control becomes a complex task. The challenge for the power designer is to consider the timing and voltage requirements of each processor and incorporate them into the overall system to ensure that the final design meets all processor requirements. Improper power supply to the processor can cause problems
