本文討論了以IP(Intellectual Property)內(nèi)核為中心的開(kāi)放式IP 核接口協(xié)議(OCP Open Core
Protocol)，包括協(xié)議特性以及基于OCP 協(xié)議的SoC(System on Chip)中設(shè)計(jì)與驗(yàn)證等，并在此基礎(chǔ)上提出了基于OCP 協(xié)議的采樣SoC 設(shè)計(jì)方案。研究表明，使用OCP 協(xié)議可避免在SoC 集成時(shí)去適應(yīng)每個(gè)內(nèi)核，系統(tǒng)集成者可以集中解決SoC 設(shè)計(jì)上的問(wèn)題，從而極大的減小SoC 開(kāi)發(fā)時(shí)間和風(fēng)險(xiǎn)。

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.
