摘要
Systems and methods are disclosed for managing memory access for low-power use cases of a system on chip. One such method comprises booting a system on chip (SoC) comprising a plurality of SoC processing devices. A trusted channel is created to a secure non-volatile random access memory (NVRAM). The method determines a power-saving software program to be executed on the SoC by one of the plurality of SoC processing devices. A software image associated with the power-saving software program is loaded to the secure NVRAM. In response to loading the software image to the secure NVRAM, each of the plurality of SoC processing devices except the one executing the software image from the secure NVRAM are powered down.
