Abstract
An electronic device includes a System on Chip (SoC) and a memory. The SoC includes a processor and a neural processing unit (NPU). The memory includes an enclave page cache (EPC), in which a validation table is stored, and at least one NPU enclave. The NPU enclave and the EPC have a trusted execution environment, which is isolated from an execution environment in which system software of the CPU is executed.
