STPC high integration X86 SOCs
[Vendor: STMicroelectronics]

These three new devices in the STMicroelectronics STPC family of highly integrated x86 PC-compatible system-on-chip (SOC) devices are fabricated in 0.25µ technology, which allows them to offer high integration, low power consumption, and low cost. Each STPC device is targeted to a slightly different class of applications:
  • STPC Elite -- the "Server Appliance Engine", for "headless applications" (i.e. without displays). Typical applications are expected to be network attached storage, firewalls, web servers, fax Servers, print servers, home gateways, routers, PBX, etc.

  • STPC Consumer-II -- the "TV Appliance Engine", for appliances that use a TV or monitor for display and video capability. Typical applications are expected to be web boxes, web-enabled TVs and TV set-top boxes, web DVD, etc.

  • STPC Atlas -- the "Internet Appliance / Terminal engine", for appliances and terminals with CRT or TFT LCD displays. Typical applications are expected to be Internet terminals, thin-client terminals, web-phones, web-pads, automotive navigation devices, and entertainment systems.
Summary of features
    Functions common to all three devices:
  • 64-bit, 133MHz X86 compatible CPU
  • 8K L1 cache
  • 64-bit SDRAM memory controller with transfer rates up to 720MBytes/sec
  • PC compatible DMA, interrupt, timing controllers
  • ISA and PCI bus controllers
  • Bus mastering EIDE controller
  • JTAG test port

    In addition to the common functions, the STPC Elite adds:
  • 16-line general purpose I/O block

    In addition to the common functions, the STPC Consumer-II adds:
  • VGA/SVGA-compatible graphics accelerator with RAMDAC
  • PAL/NTSC TV video output interface
  • Video input port

    In addition to the common functions, the STPC Atlas adds:
  • VGA/SVGA-compatible graphics accelerator with RAMDAC
  • TFT LCD display interface
  • Video input port
  • PS/2 keyboard and mouse
  • PC compatible dual-UART and parallel port
  • Dual USB host hub
  • PCMCIA / Cardbus controller
The migration to 0.25µ technology has allowed the clock speed to be increased to up to 133MHz, while reducing power consumption at 133MHz to just 2.5W (Consumer-II and Atlas) and 1.5W (Elite), at 100% CPU utilization with all peripherals exercised. The devices are packaged in low cost plastic BGA packages, and support both commercial (0 to 100 deg. C) and industrial (-40 to 115 deg. C) temperature ranges.

FUEL Database on MontaVista Linux
Whether building a mobile handset, a car navigation system, a package tracking device, or a home entertainment console, developers need capable software systems, including an operating system, development tools, and supporting libraries, to gain maximum benefit from their hardware platform and to meet aggressive time-to-market goals.

Breaking New Ground: The Evolution of Linux Clustering
With a platform comprising a complete Linux distribution, enhanced for clustering, and tailored for HPC, Penguin Computing¿s Scyld Software provides the building blocks for organizations from enterprises to workgroups to deploy, manage, and maintain Linux clusters, regardless of their size.

Data Monitoring with NightStar LX
Unlike ordinary debuggers, NightStar LX doesn¿t leave you stranded in the dark. It¿s more than just a debugger, it¿s a whole suite of integrated diagnostic tools designed for time-critical Linux applications to reduce test time, increase productivity and lower costs. You can debug, monitor, analyze and tune with minimal intrusion, so you see real execution behavior. And that¿s positively illuminating.
