DEADLOCK DETECTOR, SYSTEM INCLUDING SAME, AND METHOD FOR DETECTING DEADLOCK

摘要

The present invention relates to a system comprising a plurality of hardware blocks, a deadlock detector, and an interconnection device. The hardware blocks comprise a processor for executing instructions and a storage device for storing data. The deadlock detector monitors, in real time, an operation state of at least one target hardware block among the hardware blocks and stores debugging information in the storage device. The interconnection device electrically connects the hardware blocks and the deadlock detector. The interconnection device comprises a system bus for electrically connecting the hardware blocks and a debugging bus for electrically connecting the deadlock detector to the target hardware block and the storage device. Debugging of the system can be supported in an efficient manner and a debugging success rate can be increased by obtaining debugging information by monitoring an abnormal state of the system in real time.;COPYRIGHT KIPO 2018
