Abstract
Computer-implemented methods and associated hardware for static trusted execution environment for inter-architecture processor program compatibility are disclosed herein. A device (e.g., a Reduced Instruction Set Computing-Five (RISC-V) device), may emulate a static trusted execution environment (e.g., ARM TrustZone) using physical memory protection (PMP). A regular world may have access to only a portion of an address space of the device, while a secure world may have access to the full address space. A secure world identifier (SWID) may be stored in a configuration status register (CSR) only accessible by a mode (e.g., machine mode). When an entry is added to a translation lookaside buffer (TLB), the SWID may be added as part of a tag to differentiate secure world entries from regular world entries.
