Introduction

The STi7108M integrates in a single IC, multi-stream transport demultiplexing, an

applications CPU, a real-time CPU, A/V decode, video processing, true 3D graphics and

peripherals, audio/video DACs, digital A/V outputs, HDMI, dual eSATA ports, triple USB

ports, dual Ethernet controllers (GbE capable) and an SDIO/SD-MMC card controller.

Features

Benefits

ST40 applications CPU, ST40 real-time CPU,

ST231 applications co-processor. Each CPU

has 32KI and 32K L1 caches with 256K L2

cache for the ST40 applications CPU.

The high performance ST40 CPU for applications

and middleware, is enhanced by a real-time

companion ST40. The real-time ST40 off loads a/v

management and network protocols. The

applications CPU is complemented by a co-

processor, for multimedia processing and

security/DRM in home networks. Each ST40 works

with the ST231 to deliver unparalleled CPU

performance from a single STB SoC.

Integrated graphics processing unit (GPU).

Programmable Vertex (geometry) processor and

fragment (pixel) processor, accelerated four

times full scene anti-aliasing (4 × FSAA).

True 3D graphics and 2D vector graphics

acceleration, optimized for HD consumer digital

video applications. Compatible with the latest Open

GL ES 1.1/2.0 and OpenVG 1.1 libraries, for best-

in-class 3D graphics effects/games, font rendering

Decoded HD video can be used as textures for

visually enhanced, video rich navigation guides

and user interfaces, and provides a platform for 3D

gaming.

Latest generation of ST's video decoder with an

ST231-based multi-codec capable controller

coupled with a High Quality Video Display

Pipeline.

Decoding of advanced high definition standards for

broadcast (MPEG2, H264, VC-1, AVS) plus the

performance and flexibility for web-based content

HP@L4.1 decoding for HD PIP, and video-video

transition effects, decoding of H264 HP@L4.2

(1080p50, 1080p60 decoding) and premium

rescaling techniques open the way for high quality

viewing of enhanced HD services on the latest

generation of TVs.

Latest generation transport/security subsystem,

with enhanced performance for DVR

client/server-based home networks.

Multi-stream transport demultiplexing,

descrambling and section/data filtering. Up to 6 live

TS inputs supported.

dual e-SATA, Ethernet MAC with

MII/RMII/TMII/GMII interfaces, PCI, SD-

MMC/SDIO interface.

Extensive high speed connectivity for the widest

range of STB peripherals, such as Flash drives,

external HDDs, Gigabit Ethernet, home network

modem and memory cards.
