Pentek, Inc. announced their VME/VXS Board Model 4207 for high-performance digital signal processing and data-acquisition systems. The new board features Freescale’s MPC8641D Dual Core PowerPC AltiVec Processor and a Xilinx Virtex-4 FX Series FPGA. In addition, Pentek’s unique fabric-transparent crossbar switch bridges a wealth of gigabit serial resources, including the PowerPC and FPGA, two XMCs, dual VXS ports, dual Fibre Channel ports and two optical serial transceivers. Native protocols support PCI Express, Serial RapidIO, Fibre Channel and Aurora, all accommodated by the crossbar switch. Up to 4 GB of fast DDR2 SDRAM simplifies data buffering and boosts real-time signal processing.
The Model 4207 offers designers power, speed, and connectivity in a single-slot solution, making it well suited for wideband, data acquisition-and-recording, real-time digital signal-processing, and software-radio applications. Model 4207 combines many standard interfaces and protocols (VXS, PMC, XMC, PCI-X, PCI Express, gigabit Ethernet, RocketIO, Serial RapidIO, Fibre Channel, Xilinx Aurora, and VME64x technologies) in a single-slot solution. The crossbar switch, the two PMC/XMC sites, and the user-programmable FPGA offer designers the connectivity and flexibility needed to handle a tremendous range of tough applications. The on-board Fibre Channel interface makes the 4207 ideal for high-speed real-time recording at rates up to 800 MB/sec.
Model 4207 Features
- User-Programmable FPGA
The Model 4207 includes options for an on-board Xilinx Virtex-4 FX Series FPGA, the XC4VFX60 or XC4VFX100. Two 4X RocketIO ports provide a high-speed serial path between the FPGA and the crossbar switch for connection to other parts of the board, including the processor, VXS interface and XMC sites. These ports can also be configured as four 2X paths. The FPGA can be optionally equipped with 1 or 2 GB of DDR2 SDRAM along with 128 MB flash. Developers can take advantage of unused FPGA resources to implement custom signal-processing algorithms and to process captured data in real time. To simplify FPGA development tasks, Pentek offers its GateFlow FPGA Resources. Pentek’s GateFlow FPGA Design Kit enables the onboard FPGA to be configured by the user for implementation of custom pre-processing functions such as FFTs, FIR filters and software-radio blocks. The kit includes VHDL source files and works in conjunction with the Xilinx ISE Foundation design tools.
- Powerful Processing
The Model 4207 is equipped with either a single-core MPC8641 or a dual-core MPC8641D executing at a maximum frequency of 1.5 GHz. The very latest AltiVec Freescale PowerPC processors, they perform 128-bit parallel processing of multiple data elements (Single-Instruction, Multiple-Data Stream) and deliver DSP floating-point processing rates of up to 12,000 GFLOPS. The processor includes built-in gigabit fabric support with both 8x PCI Express and 4x Serial RapidIO serial data ports. Up to 2 GB DDR2 SDRAM is available to the processor for program and data memory, along with a nonvolatile 128 MB flash for initialization, self-test and boot code. Processor clock options are from 1.0 to1.5 GHz.
- Unique Fabric-Transparent Crossbar Switch Architecture
In addition to the processing power described, the fabric-transparent crossbar switch of the Model 4207 offers extraordinary high-speed connectivity. Since the processor configures all routing paths, the switch simply passes the gigabit serial traffic from one port to another, totally independent of any particular protocol. Multiple data streams can be sent through the switch simultaneously, even if they have different protocols. Because all high-speed interfaces on the board connect through the switch, paths can be configured to meet specific requirements. For example, XMC modules can transfer data through the switch to the on-board FPGA, to the processor, to the other XMC or to another board over the VXS connector. Similar types of connections are available for other resources, using any protocol that the connected devices support, including Serial RapidIO, PCIExpress, Xilinx Aurora and InfiniBand protocols.
- Compatible Hardware Products and Development Tools for a Variety of Platforms
The 4207 is compatible with any COTS PMC or XMC module. Pentek’s offerings include a variety of A/Ds, transceivers, digital receivers, and processing PMC and XMC modules. Pentek VxWorks and Linux Board Support Packages (BSPs) provide software developers with a complete library of hardware-initialization, control and application functions to be used in a real-time VxWorks or Linux operating environment.
