Architecture overview
STn8815A09
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 encoder/decoder Simple Profile (SP) L5 SDTV 30 fps
● MPEG4 decode up to 2 x SDTV 30 fps decode
● DVB-H class C H264 baseline L2 2Mbps CIF 30 fps
● DVB-H class B VC1 SP Main-Level 384kbps QVGA 20 fps/CIF 15 fps
● H264 decode resolution up to VGA, bit-rate up to 4Mbps
● H264 codec QCIF 15 fps
● H263 codec up to CIF 30fps
● T-DMB profile 1 and 2: H264 baseline L1.3 768 kbps CIF 30 fps
● T-DMB two streams H264 baseline profile L1.3 768 kbps QVGA 30 fps each
● JPEG encode up to 40 Mpixel/s, decode up to 10 Mpixel/s
● 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.
