Tensilica Xenergy Energy Estimator Tool
The Xenergy(TM) estimator is an energy estimator for both Xtensa(R) configurable processor and Diamond Standard processor users. By using the Xenergy tool to optimize for energy early in the SOC (System On Chip) design cycle, designers can cut processor and local memory energy requirements by up to half by making intelligent design trade-offs. Total energy to complete a task (power dissipated over time taken for the task to complete) can be dramatically reduced by customizing a Tensilica Xtensa processor. Energy improvement from processor customization can range from 2x to 83x.

TI DM6437 Digital Video Development Platform
Texas Instruments (NYSE: TXN) TMS320DM6437 Digital Video Development Platform (DVDP) is designed for its DM643x digital media processors. The DM6437 DVDP brings the complete DaVinci(TM) technology development environment to these processors by bundling a full TMS320DM6437 evaluation module (EVM) with a complete suite of DaVinci development tools and software for less than $500.

ST STP16CPS05 LED Driver
The STP16CPS05, by STMicroelectronics (NYSE: STM), is a LED driver that includes auto-power-saving features. The STP16CPS05 allows manufacturers to meet the high power-efficiency requirements of industrial lighting, signage and transport applications by guaranteeing savings of 80% compared to existing solutions.

Agilent N5431A Software
The Agilent N5431A software, which runs on Agilent 80000 Series Infiniium oscilloscopes and digital signal analyzers, helps engineers confirm that their devices conform to the XAUI specifications as defined by the IEEE 802.3-2005 10-gigabit Ethernet specification. XAUI is a chip-to-chip interface designed to transmit 10-gigabit signals over long distances on printed circuit boards. Because of its versatility, XAUI technology has been adapted for use with 10-gigabit Fibre Channel standards and other proprietary and non-proprietary standards.

TI ORing Power Controllers
TI’s TPS241x family of ORing controllers support input voltages of 3 V to 18 V, and can control power supply voltages down to 0.8 V. When used with a low Rdson N-channel MOSFET, the controllers significantly increase system efficiency and reduce power dissipation compared to today’s standard ORing diode solutions. The TPS241x devices seamlessly manage power distribution to multiple supplies, while protecting the system from potentially dangerous reverse-current or transient events by providing an extremely fast turn-off response of 130 nanoseconds. The controllers also feature a programmable turn-off threshold and an input filtering function to protect the power supply’s integrity, especially when the system must adjust to various bus characteristics caused by extreme and heavy-use operating conditions.
