Title:
DEVICE AND METHOD FOR PREVENTING BUS FROM DEADLOCKING, AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2016/062057
Kind Code:
A1
Abstract:
A device and method for preventing a bus from deadlocking, and a computer storage medium. The device comprises: a peripheral time delay unit (101) configured to monitor a bus state between a bus and a peripheral, so as to obtain a first bus state signal and send same to a state monitoring unit (103), and conduct a reset operation on a first handshake signal between the bus and the peripheral according to a received reset control instruction; a processor time delay unit (102) configured to monitor a bus state between the bus and a processor, so as to obtain a second bus state signal and send same to the state monitoring unit (103), and conduct a reset operation on a second handshake signal between the bus and the processor according to the received reset control instruction; and the state monitoring unit (103) configured to time the first bus state signal and/or the second bus state signal, and send the reset control instruction when the timed time duration exceeds a corresponding set time duration, so that the peripheral time delay unit (101) and the processor time delay unit (102) reset the handshake signals.
