Architecture overview
STn8815P14
2.1
Smart video accelerator (SVA)
Using leading-edge technology, this block is a low-power, high-performance video
accelerator that supports the following features:
● MPEG-4 simple profile level 5 video encoder and decoder; real-time up to SDTV 30 fps
(encode only or decode only).
● MPEG-4 simple profile level 3 video simultaneous codec up to CIF 30 fps.
● H.264/AVC baseline profile level 3 decoding up to VGA 30 fps.
● H.264/AVC baseline profile level 2.2 encoding up to VGA 15 fps.
● H.264/AVC baseline profile level 2 simultaneous codec up to CIF 30 fps.
● WM9/VC-1 encode/decode support.
● JPEG baseline encoder acceleration up to 30 Mpixel/s.
● JPEG baseline and extended DCT-based decoder acceleration up to 15 Mpixel/s.
● Programmable DSP (MMDSP+) for intermediate level processing, clocked at up to
166 MHz.
● Picture pre-/post-processing.
● Ultra-low power implementation.
This list of codecs is non-exhaustive, and is a baseline for the SVA performances.
2.2
Smart audio accelerator (SAA)
This high-performance block is a flexible sophisticated audio accelerator based on the
MMDSP+ programmable audio DSP, clocked up to 166 MHz, and features:
● 24-bit data path,
● ultra-low power implementation.
The audio accelerator handles:
● Speech and audio codecs: AMR (WB, NR), MP3, AAC, WMA and more,
● Sample-rate conversion to 8, 16, 32, 44.1 and 48 kHz,
● Extension of sound field and 3-D surround effects,
● Noise reduction and echo cancelling.
