【摘要】 媒体处理技术是信息技术的核心领域,随着媒体处理算法复杂度的不断增加和媒体标准的逐渐多样化,传统的ASIC或GPP的实现方式已逐渐不能满足媒体处理应用的需要。可重构媒体处理SoC采用“RISC处理器+可重构计算阵列”的可重构计算体系架构媒体处理应用提供了一种新的解决途径。基于可重构计算SoC的媒体应用解决方案需要良好的集成开发环境支持。集成开发环境包括两个重要的组件:软件模拟器和远程调试系统。针对可重构多核的SoC架构,对集成开发环境中的软件模拟器和远程调试系统进行了重新的设计。本文提出了一种基于插件机制的软件模拟器,能够很好的满足模拟调试的需求,并且模拟器结构简洁,易于扩展。针对可重构多核的远程调试需求,本文提出了一种主动式断点触发的多计算核心调试方案,该方案结构简单,易于实现,并且硬件资源少,易于扩展。更多还原

【Abstract】 The media processing technique is one of the key domains of information technology. With the increasing complexity of the media processing algorithms and the diversity of the media standard, the traditional ASIC or GPP methods can no longer satisfy the application requirement. A new approach is presented that we can solve this problem by the reconfigurable media processing SoC, which has a computing architecture composed of the RISC processor and the reconfigurable computing array.The media application solution based on the reconfigurable SoC requires a good integrated developing environment. There are two important parts of this integrated developing environment, the software simulator and the remote debug system. In this paper, we re-design these two parts of the integrated developing environment for the reconfigurable SoC architecture. An elegant and extendable simulator based on the plug-in mechanism is presented in this paper, which satisfies the requirement of simulation and debug. To meet the demand of remote debug for the reconfigurable multi-core system, we also bring forward an active break-point-triggered debug methodology for the multi-core system. This methodology has a simple architecture and is easy to realize. Besides that, it consumes a little hardware resource and is easy to extend.更多还原
