【摘要】：由于半導體工藝和VLSI設計技術的快速發(fā)展,更多復雜和高性能需求的工作被應用于嵌入式系統(tǒng)中。但是,隨著工藝尺寸越來越小,嵌入式在應用方面對帶寬的需求不斷增多,使得傳統(tǒng)總線式的片上通信架構面臨著越來越多的挑戰(zhàn)。由于NoC很好地擴展性、靈活性和傳輸并行性,使得它越來越受到人們的青睞。因此,NoC逐漸的替代了傳統(tǒng)的總線結構,成為了新興通信架構。由于在設計片上網絡時需要考慮拓撲,緩沖器大小,路由算法和流量控制機制等許多參數(shù)。因此,對全系統(tǒng)的準確評估對于NoC來說是必不可少的,所以NoC仿真器的研究也變得越來越重要。而現(xiàn)有NoC仿真器在設計過程中,需要研究人員對NoC各模塊進行描述,編寫成VHDL代碼。而不同體系結構的NoC模塊的VHDL代碼大體上是相同的。顯然,編寫VHDL代碼的這個過程不僅浪費大量時間還有可能因為人為操作在代碼方面產生不必要的錯誤。為了解決此問題,本文提出了基于自動代碼生成技術的NoC硬件仿真器-NOCsim。該仿真器采用把自動代碼生成技術應用在硬件NoC仿真器中的策略。該策略利用自動代碼生成器自動地生成與NoC各模塊相對應的VHDL代碼,然后再在FPGA上對其進行仿真。本文中,自動代碼生成系統(tǒng)主要從XML建模文件、代碼模板和基于XML和代碼模板的自動代碼生成器方面進行設計。通過實驗結果分析,發(fā)現(xiàn)本文提出的NoC仿真器在仿真相同的網絡時,在速度、面積利用率等性能方面與Booksim相比有了很大的提升,并且通過實驗可以發(fā)現(xiàn)NOCsim能夠很好地仿真三維NoC。
[Abstract]:With the rapid development of semiconductor process and VLSI design technology, more and more complex and high performance requirements have been applied to embedded systems. The traditional on-chip communication architecture is facing more and more challenges. Because of its scalability, flexibility and parallelism, NoC is becoming more and more popular. Therefore, it has gradually replaced the traditional bus architecture. It has become a new communication architecture. It is necessary for NoC to evaluate the whole system accurately because many parameters, such as topology, buffer size, routing algorithm and flow control mechanism, need to be taken into account when designing the on-chip network. Therefore, the research of NoC simulator is becoming more and more important. In the design process of the existing NoC emulator, researchers need to describe each module of NoC. Write as VHDL code. The VHDL code for different architecture NoC modules is largely the same. Obviously, This process of writing VHDL code is not only a waste of time, but also the possibility of unnecessary errors in code caused by human manipulation. This paper presents a NoC hardware emulator based on automatic code generation technology-NOCsim. this simulator adopts the strategy of applying automatic code generation technology to hardware NoC simulator. The strategy uses automatic code generator to automatically generate and. The VHDL code corresponding to each module of NoC, In this paper, the automatic code generation system is designed mainly from XML modeling file, code template and automatic code generator based on XML and code template. It is found that the proposed NoC simulator can greatly improve the performance of Booksim in terms of speed, area utilization ratio and so on when simulating the same network, and it can be found that NOCsim can simulate 3D Noc well through experiments.
