| 摘 要： | 提出了一种基于通用布线开关盒(GRB)的新型FPGA布线结构,该结构能够有效提高FPGA布线资源利用率.与VPR中的CB/SB布线结构和CS-Box结构相比,GRB结构能够进一步改善布通率和时序性能.MCNC基准电路测试结果表明:在布线开关数目相同的前提下,GRB结构能够将FPGA的综合性能平均提高4%.通过在GRB互连结构中引入快速布线通道,该结构在开关数目比CS/SB模型增加10.92%的情况下,能将时序性能提升17.50%.

| Abstract: | FPGA routing architecture exploration based on the concept of general routing box(GRB) is proposed in order to improve the efficiency of FPGA routing resource.Compared with the CB/SB routing architecture in VPR and the CS-box,route-ability and delay are improved from GRB.Experimental results of MCNC benchmark circuits show that the overall performance of the FPGA with GRB architecture is improved 4% on average with the same number of routing switches.By introducing fast path in GRB inter-connections,the tim... |
