一种多核SoC的复位管理系统设计

设计了一种适用于多核SoC系统的低功耗上电复位电路，并根据冷复位、暖复位、看门狗复位、软件复位等复位源的类型设计了一种多核SoC系统的复位管理电路。复位管理电路提供了多核SoC系统处理器、片上总线及片上各个 IP模块的复位信号，并都进行了相应的异步复位、同步释放处理。结果表明，设计的多核 SoC系统的复位管理电路能够正确控制SoC芯片复位及复位释放后的多核SoC系统正常运行。

Reset Management Circuit Design of Multi-core SoC

A low-power power-on reset circuit for the multi-core SoC is designed,and a reset management circuit is designed also accord-ing to the types of cold reset,warm reset,watchdog reset,software reset and so on.The reset management circuit provides a multi-core SoC system processor,on-chip bus and the reset signal of each IP module,and all of the corresponding asynchronous reset,synchronous release processing.The experiment results show that the designed reset circuit can supply the reset signal in the multi-core SoC and make the SoC work normally.
