Encoding/Decoding H264 doesn't consume that much either.&nbsp; My experience is that&nbsp; if you can use the video engines (hw scaler, en/decoder H264, MPEG4, H263) you'll virtually have all CPU power left.&nbsp; It takes only memory bandwith.<BR /><BR />Be aware that there is no audio compression support engine.&nbsp; If you are going to do audio+video you have to let the CPU do the audio compression/sync/echo cancellation.<BR /><BR />So regarding to your 30 fps video question, you'll have all CPU power left.<BR /><BR />Erik.<BR /><DIV></DIV></BODY></HTML> Mon, 03 Sep 2007 15:31:43 GMT https://community.nxp.com/t5/Other-NXP-Products/iMX27-CPU-Efficiency/m-p/143227#M291 eriko 2007-09-03T15:31:43Z
