通訊,多媒體,多用戶電子器件等領(lǐng)域中,片上系統(tǒng)(SoC)提供一種集成型的方案以解決各式各樣的設(shè)計(jì)問題。典型的SoC結(jié)構(gòu)包含邏輯控制模塊,微處理器,數(shù)字信號(hào)處理(DSP)模塊,嵌入式存儲(chǔ)器模塊,外部通訊接口等模塊。高速系統(tǒng)總線和低速外圍總線維持著各個(gè)模塊之間的數(shù)據(jù)通信。片上系統(tǒng)的設(shè)計(jì)主要包括數(shù)據(jù)計(jì)算,存儲(chǔ),數(shù)據(jù)通訊和I/O四個(gè)這方面。隨著處理器功耗的逐漸增加和數(shù)據(jù)密集應(yīng)用的出現(xiàn),片上系統(tǒng)的數(shù)據(jù)通訊問題正在得到越來越多的關(guān)注。系統(tǒng)的復(fù)雜度和集成度的不斷上升,設(shè)計(jì)者發(fā)現(xiàn)將通訊數(shù)據(jù)以數(shù)據(jù)包的形式投入到通訊網(wǎng)絡(luò)中相較于傳統(tǒng)的通訊方式更有利于利用有限的帶寬。換言之,由于帶寬的限制及可擴(kuò)展性差等缺點(diǎn),傳統(tǒng)的總線通訊越發(fā)難以滿足整個(gè)系統(tǒng)的通訊要求。作為一種新的通訊架構(gòu),片上網(wǎng)絡(luò)(NoC)將各個(gè)處理單元單獨(dú)離合開使得整個(gè)通訊網(wǎng)絡(luò)具有更高的通訊效率和更低的功耗。相比于傳統(tǒng)總線結(jié)構(gòu),片上網(wǎng)絡(luò)提升了整個(gè)通訊網(wǎng)絡(luò)的數(shù)據(jù)帶寬,具有更好的擴(kuò)展性和復(fù)用性,降低了通訊系統(tǒng)的整體功耗以及解決了系統(tǒng)時(shí)鐘的全局異步問題。片上網(wǎng)絡(luò)的關(guān)鍵技術(shù)主要包括網(wǎng)絡(luò)拓?fù)錂C(jī)構(gòu),路由算法,映射算法,流量控制,交換機(jī)制。路由算法決定數(shù)據(jù)包在通訊網(wǎng)...
