A true multistandard, programmable, low-power, full HD video-codec engine for smartphone SoC

Abstract

In this paper, we present IVA-HD, a true multistandard, programmable, full HD video coding engine which adopts optimal hardware-software partitioning to achieve the low-power and area requirements of the OMAP 4 processor. Unlike the approach of using separate IPs for encoder and decoder, IVA-HD uses an integrated codec engine which is area efficient, as most of the decoder logic is reused for the encoder. IVA-HD is architected to perform stream-rate and pixel- rate processing in a single pipeline (that processes one 16x16 macroblock at a time), so as to support the latency requirements of video conferencing.
