Original Press Release:
Acromag Releases PMC Analog I/O with a Re-Configurable FPGA for Applications Requiring Specialized Signal Processing
New customizable I/O modules perform high-speed, high-resolution A/D and D/A functions under the control of a user-programmable FPGA enabling use of special algorithms and logic routines.
Wixom, MI: Acromag's new PMC-AX modules enable users to implement complex, customized analog I/O embedded computing solutions. Application-specific logic routines and algorithms can be downloaded into the on-board reconfigurable FPGA, a Xilinx® Virtex-II® with up to 32,000 logic cells, to control operation of the I/O channels. These modules are ideal for high-speed, high-resolution A/D and D/A functions. Inputs are sampled at up to 65 MSPS and processed by the FPGA without CPU intervention. Typical uses include sonar, sounding systems, satellite downlink controllers, automated test equipment, and simulation instrumentation. Modules start at $2500 with varying performance levels and optional extended temperature operation (-40 to 85°C) available to meet a broad range of requirements.
Powerful and versatile, these PMC modules are designed around a reconfigurable Xilinx® Virtex®-II FPGA. A variety of models can be ordered with a 1M, 2M, or 3M-gate FPGA featuring 11.5K, 24K or 32K logic cells respectively. All of these DSP-capable FPGAs feature versatile logic resources, large on-chip memories, and a high-speed interface.
Additionally, a choice of 14-bit A/D converters provides four channels with either 20MHz or 65MHz sampling. Two channels of 900KHz 16-bit D/A are also standard on all models. The PCI bus interface is handled by a PLX® PCI 9056 device which provides 32-bit 66MHz bus mastering with dual-channel DMA support. FPGA code can be loaded from the PCI bus or from the on-board 256K x 36-bit dual-ported memory.
Offering up to 1MB of on-chip memory and 9Mb of on-board SRAM, the PMC-DX modules give users the flexibility to embed their code into the FPGA or to modify signal processing operations on the fly by loading new code into flash memory as requirements change.
An Engineering Design Kit provides basic information required to develop a custom program for the Xilinx FPGA. Utilities help users load VHDL into the FPGA, and to establish DMA transfers between the FPGA and the CPU. It is recommended that users be familiar with Xilinx development tools. Acromag's Engineering Design Kit includes a compiled FPGA file and example VHDL code provided as selectable blocks with examples for the local bus interface, read/writes, and change-of-state interrupts to the PCI bus.
For easy integration of the boards with Windows® applications, Acromag developed an ActiveX® (OLE) controls software package that functions as drivers for compatibility with Microsoft® Visual C++(TM), and Visual Basic. ActiveX can also link I/O signals to HMI devices to display and record data.
For connectivity with real time application programs, Acromag offers C libraries for VxWorks®, QNX®, and other operating systems. The libraries provide generic routines (source code included) to handle reads, writes, interrupts, and other functions. Demonstration programs enable the developer to quickly exercise the I/O modules before attaching the routines to the application program. This diagnostic tool can save hours of troubleshooting and debugging. Free Linux example programs are also available.
Acromag has been developing and manufacturing measurement and control products for more than 45 years. They are an international corporation with a world headquarters near Detroit, Michigan and a global network of sales representatives and distributors. Acromag offers a complete line of embedded I/O products including bus boards, mezzanine modules, wiring accessories, and software.
