Coprocessor, host processor, crash detection method and electronic device

A host processor having an ability to run an operating system and comprising:

• at least one circuit configured to:
• receive a handshake request from a coprocessor, wherein the coprocessor and the host processor are hardware components located in a same device;
• perform an operation triggered by the handshake request;
• and
• send, based on a result of the operation, a response to the handshake request to the coprocessor for detecting hardware crash associated with the operating system,
• wherein in accordance with the handshake request being configured to trigger the host processor to perform interrupt processing, the host processor sends different responses to the coprocessor based on whether the interrupt processing is successfully executed, to reflect a state of the host processor.

A crash detection method, comprising:

• sending, by a coprocessor, a first handshake request to a first host processor having an ability to run an operating system, wherein the coprocessor and the first host processor are hardware components located in a same device;
• monitoring a first response to the first handshake request from the first host processor;
• and
• determining a detection result of hardware crash associated with the operating system at least based on a monitoring result of the first response,
• wherein in accordance with the first handshake request being configured to trigger the first host processor to perform interrupt processing, the first host processor sends different responses to the coprocessor based on whether the interrupt processing is successfully executed, to reflect a state of the first host processor.
