GPGPU AND MASTER SCHEDULING METHOD THEREOF

摘要

The present invention relates to a general-purpose graphic processing apparatus and a scheduling method thereof. In the present invention, the instructions of the first warp group, the second warp group, the third warp group, and the fourth warp group are sequentially issued in a round-robin manner for each cycle, and the instructions are composed of system instructions, memory instructions, and arithmetic instructions. , A general-purpose graphic processing apparatus and a scheduling method thereof, which issue a system instruction, a memory instruction, and an arithmetic instruction in order of priority when issues an instruction of each warp group are disclosed. In accordance with the present invention, by sequentially processing the commands of each warp group in a round-robin method and prioritizing each command type, data hazards and memory bottlenecks that occur when commands are issued without priorities are prevented. I could do it.
