  • Patent number: 10592454
    Abstract: A system-on-chip (SoC) to perform a deadlock control on a processor of the SoC, the SoC including the processor including a plurality of central processing unit (CPU) cores, a first bus connected to the processor, a graphic processing unit (GPU) connected to the first bus, a memory controller connected to the first bus, a second bus connected to the processor, an isolation cell including a logic circuit configured to retain a signal value input to the processor according to an isolation signal, and a deadlock controller connected to the first bus and the second bus. The deadlock controller is configured to isolate the processor, which is in a deadlock state, from the first bus by applying the isolation signal on the isolation cell, and to extract, via the second bus, state information of the isolated processor in the deadlock state.
    Type: Grant
