Efficient Algorithms for MPEG-4 Video Decoding Design How-To 12/17/2002 Post a comment Efficient, programmable video decoding is critical for emerging mobile devices. J. Geoffrey Chase and Christopher Pretty from the University of Canterbury, New Zealand describe efficient algorithms for MPEG-4 video decoding and quantify the impact of accelerating co-processors for creating fully programmable MPEG-4 decoding solutions.
Estimating MOSFET switching losses means higher performance buck converters News & Analysis 12/11/2002 3 comments Lower voltages, higher current, and faster load slew rate pose a constant challenge for power supply designers. New-generation MOSFETs, high performance capacitors and new multiphase structures pose new challenges, writes this well-versed engineer.* Distributed power architectures - like Point of Load (POL) designs - will benefit from an understanding of MOSFET switching losses, he points out.
Tandem RF software programs streamline the design of power amplifiers News & Analysis 12/10/2002 Post a comment Harmonic-balance simulators - used in tandem with synthesis software that builds impedance matching networks -- can speed the design of RF power amplifiers. Engineers at Aerial Facilities in the UK show the steps they took to build a tunable 23-dB LDMOS amplifier with a center frequency in the 400-MHz range.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
