The Digital Receiver of Choice for New Sensor Systems and Program Refresh Efforts

Today’s Department of Defense (DoD) has a sharp focus on reducing embedded systems size, weight, power, and cost (SWaP-C) across virtually all military and aerospace applications. Now more than ever, SWaP-C technologies such as 3U VPX, demonstrate significant and measureable improvements in areas such as: sensor signal processing, increased mission life, and reduced total cost of system ownership (TCO). The performance, reliability, and modularity of the 3U VPX form factor has contributed to its emergence as the board of choice for new sensor systems and program refresh efforts.

In an era of DoD reduced budgets, size, weight and power reductions in electronics systems are simply not enough. The “C” for cost will need to be every bit as compelling as the technical advantages of moving to a 3U VPX system architecture. To meet this challenge, Delphi Engineering Group, Inc. (DEG) has developed a family of powerful digital receiver products that meet and exceed the DOD’s SWaP-C initiatives.

DEG Sensor Signal Processing and SWaP-C Benefits

  • Significantly Reduced Power Realization
  • Hi-Density ADC Data Conversion in a 3U Form Factor
  • Increase in DSP Slices
  • Expanded System IO Performance
  • Compelling Product and Total Cost of Ownership Savings

The VPF, VP7, and VPU: Delphi 3U VPX Digital Receivers

The Delphi family of 3U VPX Digital Receiver products add the latest cutting-edge technology to the SWaP-C story. By incorporating the latest AMD Virtex-7 and UltraScale FPGAs, as well as leading-edge data converters, Delphi provides the highest density and most capable digital receivers on the market. The Virtex-7 and UltraScale FPGA families offer significant resource and IO speed improvements over previous VME offerings. Dual AMD Virtex-6 SX family FPGAs are commonly used on 6U VME/VXS form factor FPGA carriers. When compared to the AMD Virtex-6, improved FPGA processing capability is achieved on the digital receiver using a single Virtex-7 FPGA. A DSP rich FPGA, such as the Virtex-7 VX690T, makes for a much more powerful signal processing system and decreases application latency, which is a vital requirement in real-time, Electronic Warfare (EW) embedded computing platforms.

In addition to the performance enhancements offered by the Delphi VPX products, there are important cost savings realized as well. Reduced component count, coupled with lower core and IO voltages, result in much higher signal processing per watt than traditional VME/VXS digital receiver predecessors. Reduced board costs result in lower system TCO as well. The following table illustrates several advantages of the Delphi VP7 digital receiver as compared with a legacy 6U VME/VXS receiver.

DEG VPU-085/115

DEG’s latest 3U VPX FPGA Carrier, the VPU, utilizes the AMD Kintex UltraScale XCKU085 or XCKU115 as FPGA options. The Kintex UltraScale FPGA family delivers impressive processing capabilities and supports operations such as: FFTs, FIR filters, fixed-point and repetitive processing tasks. Designed to meet the needs of challenging, embedded high-performance, digital signal processing applications, the VPU also leverages DEG’s powerful lineup of FMC+ ADC and DAC modules, delivering unsurpassed performance with high channel density on the 3U VPX form factor.

The Delphi 3U VPX boards are designed to the VITA 46.1 standard. Delphi Engineering Group is a member of the VITA Standards Organization (VSO).
