Small companies don't have researchers to comb through new technology, that's why trade shows and seminars are indispensible for staying ahead in the electronics industry. Kicking off the series of educational conferences in IIC & ESC-China 2005 is a discussion on embedded systems. The lineup will feature a roster of caliber speakers for design engineers of all stripes.

The team from Harbin Institute of Technology will lead the session showcasing its synchronous motor control without programming. It will demonstrate a DSP-based fully digital control implementation for permanent magnet synchronous motor (PMSM) to achieve speed, current and position control. A new IC will be introduced as the one-chip solution for complete closed loop current and velocity control without programming, and a high-performance DSP will be used to position loop control and implemented with software.

Meanwhile, MontaVista Software Inc., a global supplier of systems software and development tools, will tackle the growing importance of embedded operating systems (OS) for mobile devices. It's industry knowledge that MontaVista is one of the early proponents of Linux for the communications market, and it has recently opened an office in Taipei, Taiwan, the second of its Asia-Pacific expansion following its opening in Seoul, Korea in 2003.

According to the company, the increasing complexity of feature-rich devices, shorter lifecycles and the requirement to offer networking core functionality for communication devices is driving the adoption of embedded Linux. Commercial Linux companies and the Open Source community continue to evolve Linux technology to meet the requirements of mobile equipment. Hence, representatives from MontaVista says, this session will show how engineers can leverage Linux for building the next generation of intelligent mobile devices and mobile phones foreseeing 3G and 4G mobile service deployment.

Updating solutions

Presenting a practical and secure implementation of embedded routing, NextHop Technologies Inc. will detail the benefits and costs in linking embedded devices into the Internet fabric at the Ethernet or Virtual Ethernet (MPLS, VPLS) switch level, firewall level and routing level.

The conference hosted by Vitesse Semiconductor Corp., on the other hand, will discuss embedded processors taking the role of built-in self test (BIST) engines for storage products. The speaker will propose the use of embedded processors as BIST generator/checker engines that allow generation of a flexible set of patterns and frames. As storage chips are required to operate at higher speeds (3GHz to 6GHz), the need to provide a test methodology that does not solely rely on ATE patterns emerges. To address this need, BIST capabilities need to be implemented that are relatively small in gate count, operate at high speeds and provide for flexible testing environment. The session will detail BIST techniques used in a serial attachment SCSI (SAS) expander chip.

Capping off the half-day-long embedded systems conference sessions, Philips Semiconductors will undertake issues on minimizing latency and optimizing determinism with ARM microcontrollers. The session will focus on applications increasingly designed in China, such as motor control, braking systems, communications protocols with latency requirements, soft modems and closed loop control systems, require bounded response implying both good latency and determinism. The conference will describe how these attributes can be realized through a combination of system architecture features on ARM microcontrollers addressing interrupt latency, memory bandwidth with embedded Flash, closely coupled memory and debugging/emulation features that support real-time debugging.

Forum to match

Delivering to the participants a complete package of technology information wouldn't be complete without the right forum. Hence, an embedded systems forum dubbed as "The Next-Generation of Embedded Applications" will also be held that will include executives from Altera, Chipcon AS, Embedded System Sub-Association, Freescale Semiconductor, LSI Logic, Phoenix Technologies and Texas Instruments.

A trade show is often known as the great equalizer--small companies have as much exposure as the big ones when they're all positioned on the exhibit floor.

IIC & ESC-China is a good opportunity to check out the competition and assess the state of the embedded systems sector in general. The event will be staged in China's three primary electronics production hubs--Shenzhen on April 4 and 5; Beijing on April 8 and 9; and Shanghai on April 12 to 14.
