Abstract
A neural processing device is provided. The neural processing device comprises a plurality of neural processors, a shared memory shared by the plurality of neural processors, a plurality of semaphore memories, and global interconnection. The plurality of neural processors generates a plurality of L3 sync targets, respectively. Each semaphore memory is associated with a respective one of the plurality of neural processors, and the plurality of semaphore memories receive and store the plurality of L3 sync targets, respectively. Synchronization of the plurality of neural processors is performed according to the plurality of L3 sync targets. The global interconnection connects the plurality of neural processors with the shared memory, and comprises an L3 sync channel through which an L3 synchronization signal corresponding to at least one L3 sync target is transmitted.
