Abstract : constant components and output opened ports in the result of high - level synthesis lead to explicit redundancy in gate - level technology mapping . explicit redundancy can not improve the performance , but increases power consumption , enlarges circuit area and decreases its testability , so it should be removed . this paper proposes a queue loop optimization algorithm to remove explicit redundancy completely which decreases the circuit area and improves the testability 文摘:高級綜合結(jié)果中常量元件和輸出懸空端口導(dǎo)致門級工藝映射結(jié)果中存在顯式冗余.顯式冗余無助于提高電路性能,反而增加功耗,降低電路的可測試性,使電路面積增大,應(yīng)予消除.文中提出了顯式冗余的隊(duì)列循環(huán)優(yōu)化算法,完全消除了此類冗余,從而有效地減少了生成電路的基片面積,提高了電路的可測試性
