本文讨论了以IP(Intellectual Property)内核为中心的开放式IP 核接口协议(OCP Open Core Protocol),包括协议特性以及基于OCP 协议的SoC(System on Chip)中设计与验证等,并在此基础上提出了基于OCP 协议的采样SoC 设计方案。研究表明,使用OCP 协议可避免在SoC 集成时去适应每个内核,系统集成者可以集中解决SoC 设计上的问题,从而极大的减小SoC 开发时间和风险。 关键词: SoC;OCP;OCP2.1e VC;乱序传输 Research of Open Core Protocol(OCP) Abstract: In this paper, we talk about the Open Core Protocol(OCP) based on IP core, including the character of the protocol, the design and verification based on OCP protocol in SoC system, and so on. Basing on these, we advance the design method of sampling SOC system on OCP protocol. Researchs show that using OCP protocol can avoid adapting the IP core in SoC integrating, and the system integrator can else concentrate more on designing. Therefore, it decreases the time and risk of exploiting SoC system. Keywords: SoC; OCP; OCP2.1e VC; out-of-order transfer
