Abstract
Embodiments herein describe a circuit including a user domain configured to execute user functions and a hardened domain configured to communicate with the user domain. The hardened domain includes peripheral component interconnect express (PCIe) function decoding logic having a plurality of register bits and a Trusted Execution Environment (TEE) Device Interface Security Protocol (TDISP) core communicating with the PCIe function decoding logic. The TDISP core supports a plurality of PCIe functions. Each register bit of the plurality of register bits is assigned to a respective PCIe function of the plurality of PCIe functions.
