The Inner Workings of Solid State Flash: SLC versus MLC

Because all solid state flash products are not created equal and flash storage is finding its way into more and more embedded computing applications, system designers should understand the critical tradeoffs between competing technologies when evaluating flash products. Most commonly, the endurance and reliability required in end-user applications help dictate the appropriate storage technology to use. Two well-known flash storage technologies, Single Level Cell (SLC) and Multi Level Cell (MLC), offer distinct advantages, depending on a user’s needs.

VITA 66 & 67 Bringing Fiber Optic and Mixed Signal Capability to VPX

Today’s rugged embedded computing industry demands the best of technology and reliability. Driven by requirements for higher performance solutions, platforms continually evolve. Standards organizations, such as the VSO (VMEbus Standards Organization), are diligently working to bring the technology for these solutions to the mainstream. The VSO’s VPX architecture, based on Tyco Electronics’ MULTIGIG RT2 backplane connector as qualified to the VITA 46.0 standard, is the latest technology to be applied to rugged embedded computing. In addition to dealing with escalating processing, power, and cooling requirements of leading edge solutions, the VSO is now addressing the need to realize high bandwidth and high fidelity transmission via alternative media — e.g. fiber optic and coaxial wave guides. This technology is crucial in realizing the full potential of today’s cutting edge C4ISR gear, including RF intensive radar, SIGINT and IED defeat gear, as well as systems benefiting from fiber optics, including secure, long distance and high data rate communications lines.

Greg Olsen on Imaging, Space Science, and the Future of Engineering

Dr. Greg Olsen has had an illustrious career as a research scientist and entrepreneur. With degrees in physics and materials science, Olsen founded EPITAXX, a fiber-optic detector manufacturer, in 1984, and then founded Sensors Unlimited Inc. (SUI), a near-infrared camera manufacturer in 1992. SUI was sold to Goodrich Corp. in 2005. During his career, Olsen developed vapor phase epitaxial crystal growth of optoelectronic devices, including laser diodes and photodetectors for fiber-optic applications based on the material indium gallium arsenide (InGaAs). He was awarded 12 patents, wrote more than 100 technical papers, co-authored several book chapters, and has given numerous lectures to both technical and trade journal audiences.
