Method for performing system task in unprivileged mode and associated electronic device

Abstract

An electronic device includes a processor and a hardware component. The processor is arranged to utilize an instruction set architecture (ISA) to transmit a first request with a first verification key to a hardware component, for requesting the hardware component to execute a system task in an unprivileged mode, wherein the ISA corresponds to the hardware component, and the system task requests to access a target hardware address. The hardware component is arranged to determine whether to access the target hardware address according to the first verification key.

Dependencies are inferred from the claim text.
