• FastFrame1303: A PCI framegrabber available in both analog/digital and digital-only configurations for greater flexibility and cost savings
  
• FastFrame-CB: A PCMCIA (CARDBUS) frame grabber available in both analog/digital, digital-only, Camera (channel) Link configurations for greater flexibility and cost savings
  
• Fast4: A PMC board that expands the FastImage1303 PCI Board with up to eight additional Nexperia processors
  
• FastI/O: A PMC daughter-card that lets you add extra I/O ports to your FastImage or FastFrame PCI board

Philips Semiconductors (an affiliate of Royal Philips Electronics), building on award-winning TriMedia™ (very-long instruction word) VLIW processor technologies, creates and license new VLIW processor cores and sophisticated software tools and applications for advanced digital consumer products. Examples of these products include digital televisions, advanced set-top boxes, personal video recorders, video editing systems, home networking devices, security and surveillance systems, and videophones.By incorporating the Nexperia processor into Alacron’s FastSeries Family, customers and developers can significantly increase their processing power enabling them to work more efficiently and cost effectively.

PNX1302 NEXPERIA PROCESSOR

Continuing a tradition of high-performance, low-cost media processors, the Philips Nexperia (formerly TriMedia™) PNX1302 delivers more processing power to multimedia applications at a lower unit cost. The PNX1302 boosts performance through a faster clock speed and a faster main memory interface than previous Nexperia (TriMedia) processors. Datastream I/O is enhanced with a new on-chip unit for handling audio output in Sony/Philips digital format (SPDIF). Lower power consumption and a smaller footprint contribute to making the PNX1302 a more efficient and compact processing solution.

PNX1302 Features

• Processes audio, video, graphics and communications data-streams on a single chip
  
• Ideal for video-centric multimedia applications
  
• Powerful, fine-grain parallel, 180-200MHz VLIW CPU
  
• Versatile instruction set includes traditional microprocessor, special multimedia SIMD, and IEEE floating-point operations
  
• Comprehensive software development tools enable multimedia application development entirely in the C/C++ programming languages
  
• On-chip, independent, DMA-driven multimedia I/O and coprocessing units offload the CPU
  
• PCI/XIO host bus interface supports glueless interface to PCI and eight-bit microcomputer peripherals, including ROM/Flash, EEPROM, 68K, and x86 devices
  
• 16- and 64-Mbit SDRAM support up to 143 MHz
  
• On-chip DVD playback authentication/descrambling
  
• Application libraries available from Philips and third-party suppliers provide solutions for MPEG-2 decode, Dolby Digital (AC-3) ® decode, and more

• Fine-grain parallel
  
• Optimize parallelism at compile time, not during execution
  
• 5-issue slot engine
  
• 27 pipelined functional units
  
• No special scheduling logic required
  
• Executes up to 5 operations per clock cycle

STRETCH PROCESSORS

Alacron's Fast-X Series of processor boards is based on the STRETCH family of microprocessors.
Alacron’s Fast-X Series includes:

• Fast-X: A raw form factor PCI-X board with a front-end FPGA/Memory subsystem, Stretch5610, and options for 4x GigE interfaces
  
• Fast-Xe:A raw form factor 4xPCI-EXPRESS board with a front-end FPGA/Memory subsystem, Stretch5610, and options for 4x GigE interfaces and JBOD 8-way SATA controller
  
• Fast-UXGA: A raw form factor PCI-X or 4xPCI-EXPRESS board with a front-end FPGA/Memory subsystem, Stretch5610, and options for 4x GigE interfaces and JBOD 8-way SATA controller with a front end UXGA interface
  

THE STRETCH S5610 PROCESSOR

The Stretch™ S5610 software-configurable processor, the first product of the S5000 family, is based on Stretch’s revolutionary S5 engine. The S5610 dramatically boosts system performance by off-loading compute-intensive tasks from a general purpose processor. The system developers simultaneously optimize the application software and the S5610 instruction-set architecture (ISA) by tailoring the embedded pro- grammable logic within the processor engine to the application. Integrating high-performance I/Os at industry-lead- ing speeds, the S5610 offers exceptional performance enhancements to systems using 64-bit MIPS-based processors.
