【摘要】：随着集成电路技术的发展，制造工艺不断提高，基于片上系统(System on aChip，即SoC)的电子系统成为嵌入式系统的发展方向和主流。PCI（PeripheralComponent Interconnect）总线以其高性能、低成本、开放性、独立于处理器、软件透明等众多优点成为当今最流行的计算机局部总线。当今，多数嵌入式处理器并不支持PCI总线的传输，而且国内独立开发具有自主知识产权的PCI核还比较少。本文在深刻研究PCI协议的基础上，采用Verilog HDL设计了一款PCI核，，并且通过TMS320C6713DSP（Digital SignalProcessing）的外部存储器接口（External Memory Interface）简称EMIF集成到以TMS320C6713DSP为核心的SoC系统内部。通过外部存储器接口（EMIF）扩展市场上现有SoC电路的功能，可以充分利用现有资源，有效降低开发周期，节约开发成本。另外，本文还搭建了验证环境，对具有扩展功能的TMS320C6713，即具有PCI主机功能的TMS320C6713DSP进行了验证。在仿真环境下通过了对EMIF到PCI的主控制器所进行的功能仿真。为进一步将我国自主知识产权的设计与国际通用的重要IP相结合进行了有益的探索。
[Abstract]:With the development of integrated circuit technology, manufacturing technology has been improved constantly. Electronic system based on on-chip system (SoC) has become the development direction of embedded system and the mainstream of .PCI (PeripheralComponent Interconnect) bus with its high performance, low cost, openness and independence from processor. Software transparency and many other advantages have become the most popular computer local bus. Nowadays, most embedded processors do not support the transmission of PCI bus, and few independent PCI cores with independent intellectual property rights are developed in China. Based on the deep research of PCI protocol, this paper designs a PCI core with Verilog HDL, and integrates it into the SoC system with TMS320C6713DSP as the core through the TMS320C6713DSP (Digital SignalProcessing) external memory interface (External Memory Interface) for short EMIF. By extending the functions of the existing SoC circuits in the market through the external memory interface (EMIF), the existing resources can be fully utilized, the development cycle can be effectively reduced, and the development cost can be saved. In addition, the verification environment is built, and the extended TMS320C6713, that is, the TMS320C6713DSP with PCI host function, is verified. In the simulation environment, the main controller from EMIF to PCI is simulated. In order to further combine the design of China's independent intellectual property rights with international important IP, it is beneficial to explore.
