Increasing data-transfer performance in VPX systems - Story
November 16, 2017
The combination of digital simulation and high-performance calculation is radically transforming industry and research. It is now possible to develop products and services without spending precious time and dollars on replicating work already done. This is certainly the case in the military and aeronautics fields, particularly in the area of building size, weight, and power (SWaP)-constrained embedded computing architectures for use in electronic warfare and radar applications.

FPGA coprocessors for low-power adaptive beamforming in hybrid VPX HPEC systems - Story
February 10, 2017
Beamforming techniques have become very important in the fields of radar, electronic warfare (EW), sonar, wireless communication, and medical imaging. These enable continuous formation of beams from array antennas (or array transducers) towards a tracked target - or a moving user in the case of wireless communication - and cancellation of all the interfering signals coming from other angles. For tactical or airborne radar and EW solutions, the execution speed of the beamforming algorithms and the low power consumption are critical. In these situations, VPX high-performance embedded computing (HPEC) hybrid field-programmable gate array (FPGA) and CPU systems appear to be the best suited approach.

FPGA coprocessors for acceleration of shape recognition algorithms in hybrid VPX HPEC systems - Story
November 15, 2016
To reach the level of performance requested by the latest military specifications, electronic warfare (EW) systems designers rely more and more on VPX high-performance embedded computing (HPEC) platforms. To handle the global IP traffic growth - predicted to reach 132 exabytes (EB) per month in 2018, according to Cisco's Visual Network Index - electronic systems must manage the data flow in and out of the semiconductor devices. Designers of field-programmable gate arrays (FPGAs) have developed devices offering high bandwidth and performance with very high-speed interfaces that can bring superior parallel processing power. This reality enables the design of high-performance hybrid HPEC systems that can be used for such demanding applications as ultrafast shape-recognition systems.

Optical and electrical high-speed communication in HPEC systems - Story
July 26, 2016
Throughout the defense field, demand for high-volume/high-speed data transfer for high-performance embedded computing (HPEC) is growing rapidly. Systems such as software-defined radio (SDR) use advanced, complex waveforms, all of which need fast sampling and generate huge amounts of data to be transferred. Other tools, such as active electronically scaled array (AESA) radar systems, generate huge amounts of data to be processed and transmitted.

Very high-speed sampling and serial ADCs in embedded systems - Story
May 04, 2016
Latest-generation active electronically scaled array (AESA) radar systems can have thousands of TX/RX modules. High bandwidth is needed to connect each array element data converter to the FPGAs that process incoming and generate outgoing data streams. New software-defined radio systems use advanced reconfigurable modulation schemes that increase channel bandwidths and deliver unprecedented wireless data rates. To increase the performance of software radio and electronic warfare systems, it has become critical to use efficient, low-power, low-pin-count, FPGA-connected converter interfaces.

New electronic warfare architectures based on tight coupling of FPGA and CPU processing - Story
April 28, 2014
Electronic Warfare (EW) system designers are taking advantage of the performance leaps in commercial technology, driven by high-volume commercial markets such as telecommunications and cloud computing. These components such as FPGAs combine speed, high connectivity, and low power consumption for signal-processing intensive EW platforms such as fighter aircraft and Unmanned Aerial Vehicles (UAVs).
