 Model Number CodaDx11 (SD/D1)

Chips&Media's CodaDx11 is an optimally-unified multi-standard video codec IP that performs H.264 codec, MPEG-4 codec, DivX decoder, H.263 codec, VC-1 decoder, and MPEG-2 decoder up to D1 resolution at 30 frames per second in the full-duplex mode. Under our advanced design technologies, CodaDx11 not only requires ultra low-power and ultra low-clock frequency, but also provides decent flexibility in rate control, motion estimation, error concealment, error resilient, and multi-resolution/multiplex codec control.
