Training: Achieving 720p encode/decode performance by leveraging the ARM Cortex A8 and the IVA2.2
TI OMAP3xxx class of devices were originally designed with D-1 class of video codecs as the target that would run on the IVA2.2. However, the device has a very powerful ARM Cortex A8 with NEON co-processor in addition to the IVA2.2. To extend the capability of the device, Ittiam has come up with a heterogeneous multi-core implementation of multiple video encoders and decoders that utilise both the Cortex and the IVA2.2 to achieve 720p resolution performance. This presentation will cover an overview of the high-level software architecture for a video decoder and a video encoder. It will also highlight the ability of this design to transfer as much of the processing to the IVA2.2 as the device clocking gets higher so that a single design cover from the low-end OMAP3530 devices to the high-end OMAP37xx devices. The challenges with such design and the advantages and side-effects would be presented.
