Xilinx and Crossbow Technologies Announces Parallel Processing Fabric IP for Programmable System Design

10/17/2002 - Xilinx and CrossBow Technologies, a new Xilinx AllianceCOREITM program member, announced the immediate availability of CrossBow's 2D-fabric 402c multiprocessing core for providing inside-chip and chip-to-chip communications for multiprocessor programmable systems using Xilinx Virtex-IITM and SpartanTM Series FPGAs. Target applications for this core include networking, telecommunications, voice over packet gateways, wireless basestations, data communications, and other embedded systems.

With this new solution, customers can:

"We are excited to offer the industry's most comprehensive and easiest to use inter-processor communications fabric," said CrossBow's CEO Peter Galicki. "The 2D-fabric eliminates system communication bottlenecks and routing congestion through a 2-dimensional mesh topology that distributes data routing logic over the entire design area. It also presents a simple memory-like interface to handle simultaneously occurring transfers in a strictly deterministic fashion to drastically streamline system integration and verification inside Xilinx FPGAs."

The 2D-fabric IP provides a uniform and scalable I/O structure for efficient integration of multiple data processing subsystems inside a single FPGA or distributed across multiple FPGAs. Designers can easily develop high-performance processor systems combining the CrossBow fabric with a combination of multiple PowerPC processors or MicroBlazeTM soft processors embedded into Xilinx FPGAs.

"Beyond traditional applications, parallel processing can be used inside high-end FPGAs to manage system complexity and data transfer latency," said Per Holmberg, worldwide marketing director for Programmable Systems at Xilinx. "The CrossBow 2D-fabric de-couples system parts so that each component can be developed and verified independently of other components, adding value in building programmable systems by reducing development time for customers."

In addition, CrossBow is shipping a hardware parallel processing demonstration system. The board features a 3x3 array of MicroBlaze subsystems connected with a mesh of horizontal and vertical data transport links. The board has nine Spartan-II FPGAs, each containing one MicroBlaze subsystem that includes the processor core, memory, 2D-fabric, and GPIO components tied together using the CoreConnectTM bus.

The 2D-fabric 402c core is available directly from CrossBow Technologies in Xilinx netlist format, with a license fee starting at $20,000. The evaluation board is also available now for additional cost. The core is available under the terms of the SignOnce IP License, the industry's first multi-vendor common license for FPGA-based IP.
