disk drive (HDD) time-shifting and web access. This
highly integrated silicon provides a wide array of features
and interfaces, including:
MPE G-2 transport demultiplexer
DVB and DE S descramblers
MPE G-2 video and audio decoders
Dolby Digital AC-3 audio decoder
Advanced graphics display list processor
150 MHz SPARC CPU with 32KB cache
Unified Memory Architecture
Multiple host interface modes:
· PCI synchronous (master, slave)
· 68K-style asynchronous (master, slave)
· Coldfire/ PowerPC synchronous (slave)
· Hitachi SH4 synchronous (slave)
Synchronous/ asynchronous Flash support
IDE / ATAPI disk drive interface (master)
OpenCable POD, DVB-CI, or NRSS-B card interface
(master)
Interface for two SmartCards
IE E E 1394, USB Host, IDC, IE E E 1284 Peripheral,
Modem DAA, UAR T, Infrared, SPI, and GPIO interfaces
Digital video encoder (DE NC)

1.1 Product Benefits
The AViA-9600 is a fourth generation design with a
powerful SPARC processor (along with four other
embedded RISC processors or DSPs), advanced graphics
engine, extensive audio feature set, and a comprehensive
set of I/ O peripherals.
Key benefits:
Platform for digital time-shifting – hard disk (IDE )
interface, copy protection, and trick play modes
Support for sophisticated user interface – advanced
graphics display list processor, copy engine, color
expander, and enhanced text display
Home peripherals connectivity via USB, IE E E 1394
and 1284
BOM cost reduction – unified memory, integrated
peripherals, and soft modem
Flexible solution – architecture that allows
customized and software-configurable transport
demuxing and A/ V decoding, as well as a choice of
external CPUs (plus the internal host)
Support for bandwidth-demanding applications – high
performance CPU, DDR SDRAM, dedicated graphics
accelerators, as well as multiple DMA channels
Worldwide deployment support – multiple CAS,
descrambling algorithms, and transport formats
Superior display quality – crisp slow motion with
progressive scan output, flicker filter
Home theater experience – versatile audio support
with MP3, MPE G-2 5.1, AC3 and DTS support
