PMC module carrier card for embedded systems features PCI Express bus interface

Acromag’s APCe8670 carrier card provides an easy and efficient solution to interface a PMC mezzanine module to a PC across the PCI Express (PCIe) bus. Engineers can plug Acromag’s FPGA modules or other PMC modules onto the carrier card to perform a variety of signal processing functions. A bridge chip handles the PCI-X to PCIe conversion between the plug-in PMC module and the host computer. The carrier’s PCIe x4 interface supports up to four serial lanes for rapid data transfer. These carriers are designed for high-performance industrial and scientific research computing systems. They can test advanced systems for defense and aerospace applications that will be deployed later on rugged embedded computer platforms such as VME, VPX, or CompactPCI.

Three PMC PCI-X bus sockets interface through a bridge to the carrier’s PCIe x4 edge connector. The other PMC socket routes 32 LVDS I/O to a rear SCSI port for board-to-board communication. An integrated fan provides a constant airflow across the PMC module since most PCs cannot provide sufficient cooling to dissipate heat generated by large FPGA devices. The carrier card is also ready for conduction cooling with a thermal frame.

Acromag offers many compatible PMC FPGA modules with configurable logic elements for algorithm acceleration, DSP, communication, and adaptive computing functions. A JTAG connector supports Xilinx programmer for use with hosted FPGA modules. Typical applications include image processing, simulation, protocol conversion, signal intelligence, and in-circuit diagnostics. Software development tools are available for VxWorks, Linux, and Windows environments. These function libraries provide example routines or DLL driver support with C source code to save time.
