摘要：In this paper, a warp scheduler is proposed for the improvement of multi-core stream processor based GP-GPUperformance.The proposed warp schedulersaredivided into odd and even warps,which are issued separatelyby applying the dual-warp issue.Furthermore, it can simultaneously process up to four instructions because each warp can issue two instructions through superscalar issue. The superscalar issue has a limitation in that it cannot simultaneously process two instructions having data dependence. To solve this limitation, thewarp scheduler determines the instruction issuance by testing the issuing condition of the multi-core processor and the read/write register dependence.For scheduling algorithm, the round-robin algorithm was used.To measure the performance of multi-core stream processors, the Gaussianfilter maskprocessing result of the GP-GPU using the proposed warp scheduler was compared with that of the multi-core CPU on various embedded platforms. The experiment results showed that the processingspeed of the GP-GPU using the warp scheduler was 6-7 times faster.The GP-GPU also performed better on animage processing application.
