4DSP adds advanced DSP to PCIe-capable systems

4DSP has unleashed a PCI Express (PCIe) card with advanced digital signal processing (DSP) capabilities. Having multiple I/O options, the PC820 offers eight lanes of PCIe Gen 3 and up to two FMC (FPGA Mezzanine Card—VITA 57.1) sites that are closely coupled to the onboard Xilinx Kintex UltraScale FPGA and 4GB of DDR3 SDRAM.

4DSP's PC820

The PC820 has two serial peripheral interfaces: a single-lane SFP+ module and a dual-lane Samtec FireFly connector. It is designed for software defined radio (SDR), RADAR/SONAR imaging, data centre high-speed communication and analogue/digital signal processing among other uses. According to the company, the card is an excellent choice for demanding applications that require large band signal digitisation or generation through the use of accelerated frequency-domain algorithms.

The front side FMC site is located on the primary side of the board, and remains within the envelope of a single-slot PCIe card when populated. Optionally, a second FMC site is available on the backside of the PC820, with the FMC front panel occupying the front panel of the adjacent PCI Express slot. For a lab test environment or custom system, the PC820 can be operated in a stand-alone mode where power is supplied through the PCIe power connector.

The card supports 4FM GUI to monitor voltage and temperature; perform memory tests; measure the PCIe bandwidth; update FPGA firmware; and access StellarIP. Data analyser is also used to enable the real time display of digitised data.
