PMC-LX: Reconfigurable Virtex-4 FPGA with plug-in I/O
• LVDS I/O and Plug-In I/O Modules
• XC4VLX40/60 FPGA with up to 60K logic cells and 64 XtremeDSP slices
Acromag's PMC-LX boards use a high-performance Xilinx® Virtex-4TM FPGA, but maintain a relatively low price point. They are optimized for high-performance logic, featuring a high logic-to-feature ratio and a high I/O-to-feature ratio. Two modules let you select a FPGA to match your logic requirements.
Although there is no limit to the uses for Acromag's FPGA boards, several applications are ideal for this new technology. Typical uses include hardware simulation, communication processing, in-circuit diagnostics, military servers, and telecommunication.
I/O processing is handled on a separate mezzanine card that plugs into the FPGA base board. A variety of these external I/O cards offer an interface for your analog and digital I/O signals. See the AXM I/O Card for more details. Additionally, 64 I/O lines are supported via the rear (J4) connector.
Plenty of DRAM memory is available for receipt and transfer of high-speed data from the I/O data ports on the front and rear of the board. Dual Ported SRAM memory is supplied for storage of data to be passed, via DMA transfer, to the PCI bus. One of the dual ports is attached to the FPGA and the other to the local bus.
The PCI bus interface is handled by a PLX® PCI 9656 device which provides 64-bit 66MHz bus mastering with dual-channel DMA support.
Take advantage of the optional conduction cooling for use in hostile environments. Conduction cooling provides efficient heat dissipation in environments where there is inadequate cooling air flow.
Acromag provides software utilities and examples to simplify your programming and get you started quickly. A JTAG interface enables on-board VHDL simulation.
