In　view　of　the　need　to　use　multiple　remote　controls　to　operate　separately　when　watching　HDTV,　in　order　to　reduce　the　unnecessary　operation　of　users　in　the　process　of　viewing　the　film,　HDMI-CEC　is　generated,　which　just　meets　the　needs　of　users.　At　present,　all　HD(High-Definition　Multimedia　Interface)　devices　produced　by　manufacturers　have　CEC(consumer　electronic　control)function.　CEC　function　brings　a　lot　of　convenience　to　users.　It　allows　end　users　to　control　multiple　HD　devices　with　CEC　by　using　one　remote　controller,　thus　reducing　the　number　of　remote　controls.　This　design　is　a　controller　based　on　HDMI　version.　The　Hardware　Description　Language　Verilog　is　used　to　realize　the　design　of　CEC　bus　controller　IP　core.　VCS　simulation　tool　is　used　to　verify　the　design.　The　experimental　results　show　that　the　design　meets　the　requirements　of　hdmi-cec　bus　controller　design.　This　article　mainly　talks　about　HDMI-CEC　protocol,　design　architecture,　micro　architecture,　and　software　hardware　coordination　design　method.　©　2020　IEEE.
