Introduction

The STi7108 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 display,

advanced security, STB 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 delivers over 900DMIPs, which together with the ST231,

offers an unparalleled 2500DMIPs of 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 and Adobe Flash

support. Open GL ES 2.x ready. Decoded HD video can be used

as textures for visually enhanced, video rich navigation guides

and user interfaces.

Latest generation of ST's Delta video decoder with an ST231-

based multi-codec capable controller coupled with a High

Quality Video Display Pipeline. (HQVDP).

Decoding of advanced high definition standards for broadcast

(MPEG2, H264, VC-1, AVS) plus the performance and flexibility

for web-based content decoding such as Flash, DivX, MJPEG

and Real. New capabilities such as, Dual H264 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 by an

aggregate input rate > 480 Mbits/sec.

Decryption/encryption/transcription supported for all the major

conditional access systems, local content protection, and DRM

security schemes.

Triple USB 2.0 hosts, dual e-SATA , Dual 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 controllers (eg MoCA, Wifi), DOCSIS

modem and memory cards.
