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
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.
Integrated graphics processing unit (GPU). Programmable
Vertex (geometry) processor and fragment (pixel) processor,
accelerated four times full scene anti-aliasing (4 × FSAA).
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).
Latest generation transport/security subsystem, with
enhanced performance for DVR client/server-based home
networks.
Triple USB 2.0 hosts, dual e-SATA , Dual Ethernet MAC with
MII/RMII/TMII/GMII interfaces, PCI, SD-MMC/SDIO interface.

Benefits
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.
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.
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.
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.
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.
