Abstract

Disclosed are a protection circuit and method for protecting a protected module, a storage medium, and an electronic device. The protection circuit for a protected module includes: a first detection control module, configured for determining a current state of the protected module based on a transmission signal on a control signal bus between a real control signal source and the protected module; a generation module, configured for generating test input data in response to the current state being an idle state; and a second detection control module, configured for determining an abnormality detection result for the protected module based on actual test output data output by the protected module for the test input data and expected test output data corresponding to the test input data. The embodiments of the present disclosure can effectively achieve abnormality detection on the protected module without impacting normal operation of the protected module.
