Feature list

STi5205

● High-performance CPUs for applications (ST40) and audio/video decoding (2 x ST231)

– ST40-300, dual-issue, applications CPU, 32 K instruction and 32 K data caches:

target speed > 450 MHz delivering > 800 DMIPs

● Single 16-bit DDR1/DDR2 Local Memory Interface (LMI), up to 400 MHz

● Latest generation “Delta” video decoder with ST231 programmable CPU core:

– MPEG2, H264, VC-1/WM9/AVS SD advanced video decoding

– Provides flexibility to support other codecs (DivX, XviD, H263 encode/decode)

– SD decoding or dual SD decoding, PIP and mosaic capable

– Real-time transcoding of MPEG2 SD to H264 SIF

● Advanced de-blocking and de-ringing of decoded MPEG2 SD sources based on ST’s

DSE (Digital Source Enhancer) technology with 2D analysis window and texture

adaptive filter

● ST231 CPU based audio decoder. MPEG1 I/II, MP3, Dolby Digital/DD+, MPEG4

AAC/AAC+ multi-channel audio decoding. Concurrent audio description decoding.

DD+ and AAC+ transcoding

● Main and aux video display pipelines:

– Main: high quality H and V reformatting/resizing with sample rate

conversion/filtering. Motion adaptive spatial and temporal de-interlacing for

480p/576p progressive output

– Aux: high quality H and V reformatting/resizing with sample rate

conversion/filtering

● Three independent graphics planes with H and V resize, CLUT and anti-flicker filtering

● Link list based 2D graphics blitter. Up to 200 Mpixels/sec with destination alpha

blending. Capable of 3D user interface effects.

● Independent main and aux display compositions (video/graphics mixing)

● Pass-through display for graphics, main video or aux video output concurrently with

main and aux compositions

● SD display capture

● HDMI 1.3a(a) interface with HDCP copy protection. (ED/SD formats up to 480 p/576 p)

● MacrovisionTM and Dwight Cavendish copy protection support

● PAL/NTSC/SECAM digital encoder

● Six 10-bit DACs for component/composite analog video output (ED/SD formats up to

480p/576p)

● SD digital video input port, 8-bit YCbCr

● Integrated stereo audio DAC

● Six-channel audio PCM output interface

● Stereo audio PCM input interface

● Independent SPDIF output

● Quadruple external TS inputs, triple internal TS from memory

a. Full compliance to all features of v1.3a, excluding Deep Color, enhanced colorimetry (xvYCC, gamut

metadata), and DST/DSD audio.
