2/20/2004 - Semiconductor intellectual property (IP) provider CAST, Inc. announced a new 1394a core that implements a link layer controller for the high-speed digital bus known commercially as FireWireTM and i.LinkTM.
The IEEE 1394a standard was developed for use with digital video and other demanding applications arising from the convergence of computers and consumer products. It defines a high-bandwidth serial interface with real-time data transmission rates of 100, 200, and 400 Mb/sec. It features automatic bus reconfiguration (plug and play), support for connecting up to 63 devices with freeform daisy chaining and branching, and guaranteed full bandwidth and transfer rates for all connected devices. Apple Computer pioneered the technology under the trademarked name “FireWire,” and Sony Corporation uses it in many products with the trademarked name “i.Link.”
CAST’s C1394A core conforms to the IEEE 1394-1995 and 1394a-2000 standards, and provides all the specified features and capabilities. It is similar to the popular Texas Instruments TSB12LV32 General Purpose Link Layer Controller, but includes a 32-bit APB interface for easy connection with an AMBATM bus host system. (AHB and other standard interfaces are also available.) The core can interface with any 1394-compliant physical layer (PHY) device, and it includes easy-to-apply C-language software functions for all basic operations (optional software packages provide the transaction layer and serial bus management function).
The C1394A core is FPGA-proven and has been exercised in a FireWire video camera demo system.
The core ships with full user documentation and a complete verification environment. An additional verification option further facilitates system-on-chip testing by serving as a working physical layer and emulating bus traffic and other nodes on the bus.
The C1394A core was developed by CAST partner Evatronix SA, based in Poland (www.evatronix.pl). Commercial shipments will begin later this quarter. Pricing varies by configuration and license type; contact CAST for details.
