A Soft Control Architecture: Breakthrough in Hard Real-Time Design for Complex Systems

How to cut costs, improve quality, and differentiate your products with a software-based approach to machine automation OEMs have long relied on expensive, cumbersome hardware like FPGAs and DSPs for precision motion control. But new advances in software-based machine automation are changing that paradigm, with huge potential benefits.

Safety in SoCs

Accelerating the Road to ISO 26262 Certification With Processor IP Today’s system-on-chip (SoC) designs are becoming more complex, increasing the pressure on verification and design teams to deliver fully functional designs. Recent studies have shown that over 50% of the development time on a complex IC is now being spent on verification, revealing the severity of the problem project teams are facing. As more SoC designs are used in electronic systems deployed in safety-critical applications, adhering to functional safety standards such as ISO 26262 has become an important consideration when defining the verification methodology. This white paper outlines the key requirements for ISO 26262 certification and demonstrates how to accelerate the development of safety-critical IP and SoCs through the use of out-of-the-box safety-ready IP with advanced verification qualification tools and methodologies.

Improved Digital Map Rendering Method

Software for aeronautics collision avoidance can be used in aerospace satellites, automobiles, scientific research, marine charting systems, and medical devices. Armstrong Flight Research Center, Edwards, California Data adaptive algorithms are the critically enabling technology for automatic collision avoidance system efforts at NASA’s Armstrong Flight Research Center. These Armstrong-developed algorithms provide an extensive and highly efficient encoding process for global-scale digital terrain maps (DTMs) along with a real-time decoding process to locally render map data. Available for licensing, these terrain-mapping algorithms are designed to be easily integrated into an aircraft’s existing onboard computing environment, or into an electronic flight bag (EFB) or mobile device application. In addition to its use within next-generation collision avoidance systems, the software can be adapted for use in a wide variety of applications, including aerospace satellites, automobiles, scientific research, marine charting systems, and medical devices.

Interactive Diagnostic Modeling Evaluator

Ames Research Center, Moffett Field, California NASA’s Ames Research Center has developed an interactive diagnostic modeling evaluator (i-DME) tool to aid in modeling for noise and lag in the data and debugging of system models when fault detection, isolation, and recovery results are incorrect. i-DME is designed to dramatically speed up the modeling debugging process. Often what hinders human-led model developments are 1) the sheer size of playback files, 2) the modeling for noise and lag in the data, and 3) debugging the fault/test relationships in the model. To alleviate these problems, i-DME can automatically play back very large data sets to find time points of interest where userset performance criteria for detection and isolation are violated. i-DME modifies the diagnostic model through its abstract representation, diagnostic matrix (D-matrix). The types of modifications are procedures ranging from modifying 0s and 1s in the D-matrix, adding/removing the rows/columns, or modifying test/wrapper logic used to determine test results. This software has the capacity to be applied to any complex system for navigation or generation of large amounts of complex data to identify, prioritize, and resolve errors in a self-correcting manner.

High-Fidelity 3D Electromagnetic (E&M) Propagation Modeling Tools

NASA’s Jet Propulsion Laboratory, Pasadena, California For a future potential radar sounder mission to small celestial bodies like comets and asteroids, it is important to understand the interaction between propagating waves and interior geophysical structures. In general, it is not easy to build a software model capable of handling relevant dimensions with high numerical accuracy. Researchers often rely on a scaled-down model that cannot fully represent physical phenomena.
