Abstract
Boot of a PCIe EP coupled to a RC by a PCIe bus comprises setting, by the PCIe EP, a program counter of a CPU of the PCIe EP to an address indicative of an address of memory of the RC which stores the boot software to execute. A memory transaction to read, by the PCIe EP via the PCIe bus, a portion of the boot software stored in the address of the memory of the RC which store the boot software is performed followed by receiving by the CPU the portion which is read from the memory of the RC via the PCIe bus and PCIe controller of the EP. The portion is stored by the CPU in an instruction cache of the CPU and the CPU of the PCIe EP executes an instruction of the portion of the boot software that is received.
