Sequentially propagating instructions of thread through serially coupled PEs for concurrent processing respective thread on different data and synchronizing upon branch

摘要

A systolic data processing apparatus includes a processing element (PE) array and control unit. The PE array comprises a plurality of PEs, each PE executing a thread with respect to different data according to an input instruction and pipelining the instruction at each cycle for executing a program. The control unit inputs a new instruction to a first PE of the PE array at each cycle.
