摘要
常用软件编码方法在用于H.264标准时,很难实现对高清视频的实时解码。为此,提出软硬件协同设计的方法,对H.264高清编码器系统进行软硬件划分及任务分配,分别设计软件部分和硬件部分。建立软硬件协同仿真环境,对整个系统的功能和性能进行仿真,采用约束随机验证的方法提高验证的功能覆盖率。仿真结果表明,该编码器系统能够对1 024×768像素的图像帧进行编码,满足实时编码的要求。
As the commonly used software coding method in H.264 standard is difficult to realize the high definition video real time decoding,this paper presents a method of software and hardware of co-design H.264 high definition encoder for software and hardware division and the distribution of the task,and designs its software part and respectively hardware parts.After the completion of the design,build software hardware co-simulation environment for the whole system function and performance simulation,and using the Constrained Random Verification（CRV） method to improve the verification function coverage rate.Simulation results show that the encoder system on 1 024×768 pixel image frames is encoded,fully meets the requirements of real-time encoding.
