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, the instruction of each warp group is sequentially processed in a round-robin manner, and priority is given to each instruction type, thereby preventing performance degradation due to data hazards and memory bottlenecks that occur when an instruction is issued without priority. I could do it.
