Abstract
A processing system stores a boot image for a critical domain of a system-on-a-chip (SOC) at a bank of a static random-access memory (SRAM) that is shared by the critical domain and a non-critical domain and that is powered independently from the non-critical domain. The SOC includes a secure processor that loads the boot image to the bank of the SRAM and then blocks subsequent write access to the bank. Because the critical domain is powered independently from the non-critical domain, the bank of the SRAM retains the boot image without regard to the power state of the non-critical domain. In addition, the critical domain implements a boot process that is decoupled from a CPU at the non-critical domain, ensuring that the critical domain can initiate a re-boot sequence even if the non-critical domain is not powered.
