    Abstract: An apparatus and method of fast PCIe multi-function device address decode utilizing a target function data look up table. One or more decode directives (e.g., targeted functions) are provided within the PCIe request packet, thereby eliminating the need for target function search during the decode process in the endpoint device. This enables single-decoder single-step decode implementation in complex multi-function devices.
