TOKYO, JAPAN: Freescale Semiconductor has introduced the QorIQ P1022 dual-core processor with advanced power management capabilities to support energy-efficient designs for embedded applications. The low-power, high-performance P1022 processor helps embedded systems designers satisfy green-energy mandates while achieving low overall system cost.
Based on 45-nm process technology, the P1022 processor is the sixth announced member of Freescale’s QorIQ multicore product line. The device offers best-in-class energy efficiency and a broad range of performance and integration capabilities. It is ideal for applications where performance and energy efficiency are essential, including printing and imaging products, video surveillance technology, storage equipment, and industrial automation and control applications.
“Increased governmental and regulatory focus on energy efficiency for all classes of embedded products presents new challenges for embedded systems designers and developers,” said Brett Butler, vice president and general manager of Freescale’s Networking Processor Division. “Freescale has designed the QorIQ P1022 processor with advanced power and energy management capabilities to help multicore processing applications meet increasing energy-efficiency standards while enabling low system cost.”
The device features a dual gigahertz core system for concurrent applications processing, delivering networked services, media processing and compelling user-interface capabilities. Built on two Power Architecture cores ranging from 600 MHz to 1 GHz, the P1022 features high-speed triple PCI Express interconnects, hardware acceleration, 256 KB L2 cache and DDR2/3 memory options. The device also integrates Serial ATA interconnect technology and SD/MMC controllers for easy connectivity to integrated storage devices. Freescale additionally offers a single-core processor called the QorIQ P1013 with the same set of system peripherals, interconnect technology and advanced power and energy management features.
Sophisticated power management features include Freescale’s Jog technology, which dynamically lowers power consumption for cyclical workloads. The P1022 processor also offers network-aware packet-lossless deep sleep standby capabilities, enabling the creation of embedded systems that achieve 1 watt AC network standby while maintaining fast, responsive networking for on-demand processing.
Support for both asymmetric multiprocessing (AMP) and symmetric multiprocessing (SMP) operating modes enables performance scaling and flexibility. Freescale has demonstrated up to 82 percent improvement in AMP and up to 78 percent in SMP in test applications with the P1022 processor, versus a single-core device operating at the same clock rates.
Designers can utilize one core for implementing user interfaces and value-added network services, while the second core performs media processing in applications like multi-function printers, video surveillance equipment and remotely stored media servers in an AMP environment. Utilization of SMP in networked media processing is equally efficient, since the P1022 can also parallelize a single workload in SMP mode to help increase overall system speed and responsiveness.
The P1022 processor achieves cost savings at the system level by integrating system peripherals including gigabit Ethernet, IEEE 1588, USB 2.0, SATA, SD/MMC, DUART, SPI, I2C and a user interface LCD controller. In addition, it uses a printed circuit board that is routable in four signal layers to further reduce costs. The P1022 product features cost-effective boot modes including NAND flash, high-speed serial flash and removable SD/MMC.

Dialog, TridonicAtco joint development centre for lighting control ICs
KIRCHHEIM & TECK, GERMANY & DORNBIRN, AUSTRIA: Dialog Semiconductor and TridonicAtco, a member of the Zumtobel Group, have established a joint development centre for next generation energy efficient lighting technology.
The move intensifies the longstanding successful collaboration between the two companies in the development of integrated circuits, such as the recently launched TridonicAtco XITEC chip family.
The development centre, drawing on the services of international experts in the fields of lighting, power management and signal processing technology, is to be based in two locations in Austria: Graz and Dornbirn.
The charter of the joint team is to develop innovative control ICs both for conventional light sources, such as fluorescent or HID lamps, and for emerging LEDs.
These devices will ensure the optimal control and regulation of light sources, at the same time maximising their service life and, through intelligent control using advanced digital signal processing, will be fundamental in minimising energy consumption.
The move will also further enhance the patent and intellectual property portfolio of the companies in the field of state of the art lighting control and semiconductor process technology.
"Semiconductors play an important role in improving power efficiencies, in reducing global energy consumption and in environmental sustainability," said Dr Jalal Bagherli, CEO of Dialog Semiconductor.
"The lighting industry is going through a period of rapid technological change. In establishing this partnership, I am delighted to be bringing our relationship with this industry leader to the next level as we together leverage our expertise to create the most power-efficient lighting systems possible."
TridonicAtco CEO Walter Ziegler was similarly enthusiastic about the new partnership: "By providing energy-efficient circuitry we enable our customers to realise sustainable lighting solutions. Through the new development centre we will be able to shorten our development cycles and to further reinforce our leading patent position in the field of state-of-the art lighting control gear.
"At the same time, this move sends out a signal that, despite the tough economic times, we are stepping up our investments in research and development to safeguard the long-term success of our business."

Jennic's wireless MCU plays key role in ensuring greater energy efficiency
SHEFFIELD, UK: Jennic’s JN5139 wireless MCU has shown its worth in the ongoing fight to protect the environment.
These 16MHz MCU devices have been used by Gloucestershire based electronics consultancy firm MicroWatt to give its KnowWatt energy monitoring systems reliable RF data links.
The JN5139 is optimised for low power operation, and boasts a work rate of 3MIPS for every mA of current that it draws. The device has a 32-bit RISC core, 192kB of ROM and 96kB of RAM. It incorporates a 4-input 12-bit analog-to-digital converter, two 11-bit digital-to-analogue converters, and a temperature sensor within its 8x8mm, 56-lead, QFN package.
The integrated 2.4GHz transceiver is fully compliant with the IEEE 802.15.4 communications standard, with support for bi-directional data transfer at rates of up to 250kb/s over a choice of 16 different channels.
As a result of their contribution to the KnowWatt energy monitoring system, Jennic MCUs are set to be featured in eco-village projects of the future. These villages aim to be the template for how communities will live, and will be able to fully conform with the government’s goal that by the year 2016 all new homes built in the UK should be carbon neutral.
It is not just in the domestic environment that this technology can make a difference however. KnowWatt wireless monitoring systems are being installed in many commercial premises too. A system that was recently put into operation at the Retreat wine bar in Stroud has had a huge effect on reducing the business’ heavy electricity consumption levels.
It has allowed the management to do in depth analysis on the bar’s electricity
consumption throughout the day. This has led to the re-education of staff, making them aware of several uneconomical working practices, as well as identifying sources of wasted energy. By utilising the KnowWatt system (with its many Jennic JN5139 MCUs) it has been possible to cut the Retreat’s overall power consumption by a figure of 1kW/hr (with a 40 percent reduction in the electricity needed for its cellar operations).
The advantages of using an energy monitoring system are clear, and with households and enterprises throughout the country looking to keep spiralling utility bills in check, widespread proliferation is certain to follow.
As Simon Clegg, MicroWatt’s MD, states: “With a greater number of installations of these monitoring systems taking place in the future, we expect most customers to be able to see a return on their investment within six to eight months.”
