Abstract: Systems, methods, and computer programs are disclosed for securely booting a system on chip. One embodiment is a system comprising a system on chip (SoC) and a virtual collated internal memory pool (VCIMP). The SoC comprises a bootable processing device having a first internal memory, a read only memory (ROM), and one or more bootable processing subsystems each having a dedicated internal memory. The bootable processing device is configured to execute a bootloader in the ROM. The VCIMP provides time-shared control and access to the one or more bootable processing subsystems during execution of a boot sequence. The VCIMP comprises a contiguous logical-to-physical address mapping of the first internal memory residing on the bootable processing device and the dedicated internal memories residing on the corresponding one or more bootable processing subsystems.
