随着高清影音时代的到来，新的高清多媒体接口技术也渐趋成熟。本文研究了高清多媒体接口的编码和解码功能，并采用硬件描述语言实现高清多媒体接口规范定义的编解码功能。首先对高清多媒体接口的整体信道传输过程进行了分析和分解，并阐述了三个数据周期传输时间及其解码方式的不同。在此基础上对编解码功能进行了模块划分，采用分层及模块复用至顶向下的设计方法。最后通过NC-Verilog仿真工具仿真验证代码功能的正确性。

The arrival of the era of high-definition multimedia, including both video images and sounds, requires new definition and realization of the interface technology. The encoding and decoding functions of high-definition multimedia interface are studied in this paper. Using the high-definition multimedia interface specification (HDMI), the front-end design of the encoding and decoding functions is implemented with the hardware description language - Verilog. First, we analyzed and decomposed the transmission process of the whole channel in the high-definition multimedia interface, and elaborated the difference of transmit time in three data periods and decoding methods. Second, based on the analysis, we divided the functions into sub-modules and adopted hierarchical and IP-reuse methodology in our implementation process. Finally, we tested the correctness of the design implementation with both functional verification and circuit simulation.
