ATRIA LOGIC, INC.

OVERVIEW

The AL-MPEG2E-SW Video Encoder is MPEG-2 part 2 Main 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 both Simple profile and Main profile at Low and Main levels. The design can handle very
low bitrates in both variable and constant modes. The design can encode up to 1080pHD resolution videos, it
also supports B frame prediction which can predict with one reference picture in each way. 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.
