基于FPGA的HDMI_CEC设计与实现

Design and Implementation of HDMI_CEC Based on FPGA

在分析CEC协议的基础之上,提出了一种利用较少的逻辑资源实现CEC功能模块的方案,利用可综合的Verilog语言在Quartus II 10.0及ModelSim 6.5g平台下完成了电路的设计综合仿真及FPGA验证。从仿真验证结果看,本设计与HDMI接口结合后能运用于各类音视频传输系统。

Based on the analysis of the CEC protocol, an implementation scheme of HDMI-CEC is put forward. By using synthesizable Verilog language in the Quartus II 10. 0 and ModelSim 6. 5g platform, the simulation of CEC circuit and FPGA verification are realized. The simulation results show that this design can be used in all kinds of audio and video transmission systems after the combination of the HDMI interface.
