ATRIA LOGIC, INC.

OVERVIEW

The AL-H264E-SW Video Encoder is H.264 Baseline Profile implementation for Mobile Platforms. The software
IP is optimized with innovative and efficient algorithms that Atria Logic has developed for low-power and high
efficiency mobile applications. The implementation is highly efficient in terms of speed and memory footprint. The
IP creates high quality streams at low bit-rates.

Designed for easy reuse and optimization, the Software IP runs on several platforms and operating systems. The
design has been proven on Tilera TilePro64, ARM7, ARM9, ARM9E and ARM11. The design has been tested in
both Windows and Linux environments.

The design can encode Baseline profile up to level 3. The design can handle very low bitrates in both variable and
constant modes. The design can encode up to 1080pHD resolution videos. The various unique qualities of this
particular design consist of support of all block sizes as specified by the standard for inter and intra prediction,
support of half and quarter pel prediction in motion estimation, supports unconstrained intra prediction mode and
motion estimation over frame boundaries mode, in-loop deblocking filter is implemented. The rate control
algorithm is proprietary which changes the Qp values in a single pass. The mode decision for best prediction is
done using rate-distortion algorithm for good PSNR values.
