FPGA Reconfiguration with Accelerated Bitstream Relocation

Goddard Space Flight Center, Greenbelt, Maryland Partial bitstream relocation (PBR) on field programmable gate arrays (FPGAs) is a technique to re-scale parallelism of accelerator architectures at run time and enhance fault tolerance. PBR techniques have focused on reading inactive bitstreams stored in memory, on-chip or off-chip, whose contents are generated for a specific partial reconfiguration region (PRR) and modified on demand for configuration into a PRR at a different location.

Real-Time LiDAR Signal Processing FPGA Modules

Goddard Space Flight Center, Greenbelt, Maryland A scanning LiDAR, by its inherent nature, generates a great deal of raw digital data. To generate 3D imagery in real time, the data must be processed as quickly as possible. One method of discerning time-of-flight of a laser pulse for a LiDAR application is correlating a Gaussian pulse with a discretely sampled waveform from the LiDAR receiver.

Advanced, Ultra-Low-Loss, High-Frequency Package Module

This module could improve performance of radiometers, high-resolution spectrometers, radars, and communication receivers and/or transmitters. NASA’s Jet Propulsion Laboratory, Pasadena, California As electronic circuits approach submillimeter wavelength frequencies (300 GHz) and higher, the traditional low-loss method of packaging electronic circuits in waveguide modules for guiding the signal requires more attention. The reasons are that circuits at higher frequencies have lower signal power levels due to limited gain and output power of semiconductor devices. As a result, the power lost by signals in the waveguide propagation environment becomes even more important at higher frequencies. In addition, previous efforts have based higher-frequency waveguide modules on existing lower-frequency module concepts and internal components.

Next-Generation Electronics Innovations for NASA’s Space and Commercial Future

In 1964, NASA’s Electronics Research Center (ERC) opened in Massachusetts, serving to develop the space agency’s in-house expertise in electronics during the Apollo era. The center’s accomplishments include development of a high-frequency (30-GHz) oscillator, a miniaturized tunnel-diode transducer, and a transistor more tolerant of space radiation. Another development was in the area of holography. At the ERC, holography was “used for data storage, and has permitted a remarkable degree of data compression in the storing of star patterns.”

Successful Test Management For Systems Engineers

Designing a reliable test strategy requires broad, strategic thinking. The goal of verification is to ensure you release a best-quality system that meets customer expectations as documented in your early design concept and requirements gathering phases. To maximize the value of your test process, test your product objectives early.

Delivering Roadworthy Designs: Automotive Electronics Circuit Protection Overview, Applications & Standards

Today’s automotive designs include nearly 100 microprocessors; that number is expected to double in five years. From in-dash displays to connected technologies and safety systems, all onboard electronics require circuit protection to maintain reliability. The major sources of electrical hazards in automotive systems are electrostatic discharge (ESD), switching loads in power electronics circuits, and lightning. Overcoming transient surges that can harm the vehicle’s electronics, whether under the hood or in the cabin, is one of the biggest obstacles of system design.

How to Avoid PCB Re-spins when IC’s Change or are Obsoleted

Working with printed circuit boards (PCBs) for sophisticated military, aerospace, or medical systems can be a frustrating – and expensive – exercise, particularly when the customer requests “a simple upgrade” or modification after the boards have been made or after deployment. Thanks to Murphy’s Law, these “simple upgrades” are never as simple as they should be. Aries has developed a unique solution that can save you from having to re-spin your PCB due to IC obsolescence or package change.
