The Nexus 5001 Forum today announced the recent ratification of its Bylaws by member companies and also set expectation that a substantial update to the IEEE-ISTO 5001™-1999 standard will be released in 2003.
Approved by supermajority of the Forum’s membership, the Bylaws strengthen the relationship among the 15 current member companies of the Forum. Prior to approving its Bylaws, the Forum had operated under a common Memorandum of Understanding(MOU).
“The ratification of the bylaws is an important step forward in the formalization of the activities of the forum,” says Professor Arnold Berger, the Forum’s Secretary/Treasurer. “The Bylaws clearly outline voting procedures, the management of intellectual property, membership commitments and the approval processes needed to ratify the specifications created by the forum’s technical committees. Thus, the Bylaws codifies all the essentials needed to run a standards organization.”
Professor Berger, as Secretary/Treasurer, works alongside fellow Forum officers chairman Michael Healy of Ashling and vice-chairman Ron Stence of Motorola. The three men sit on a seven-member Steering Committee that also includes member companies ETAS, Inc.; WindRiver Systems; Infineon Technologies; and Delphi. The Forum’s 2003 Steering Committee will be determined at the groups next Annual Meeting, scheduled for April 2003 in San Francisco.
With its operating procedures safely in place, the Forum is focusing its attention on an update to IEEE-ISTO 5001™-1999 standard, the industry standard that specifies an open, global, general-purpose interface for development, debugging and optimization of embedded microprocessor systems.
“It’s been almost four years since our first release of the 5001 specification, and a generation in the embedded microprocessor industry is about 18 months long. Almost immediately after the first release we’ve been working toward correcting uncertainties in the specification, updating some parts of it, and keeping it current with the evolution of the processors it services” says Berger. “In the next release, which will happen sometime in 2003, implementers of the standard will see that we’ve extended the scope quite a bit from the 1999 version, which hopefully, will keep it relevant to the needs of developers designing with Nexus-Compliant embedded microprocessors.”
The Nexus 5001 Forum membership spans the semiconductor, development tools and automotive electronics industries. Although the initial focus of the consortium was on the stringent requirements of automotive power train applications, the overall goal of the Forum is to continue the development of state-of-the-art, easy to use, high performance microcontrollers. The Forum plans to release an updated version of IEEE-ISTO 5001™- 1999 mid-year 2003. generation in the embedded microprocessor industry is abou
Current members of the Forum are: Ashling Microsystems, Motorola, iSystem GmBH, ETAS Inc., Infineon, Alphamosaic, Delphi Auto, Lauterbach, National Semiconductor, Nohau, Siroyan, Wind River, Hitachi, ST and IAR Systems.

1 December 2000 — The Nexus 5001™ Forum has given a strong welcome to the recent announcement by Motorola of its launch of the industry’s first embedded processor with a Nexus 5001 Class 3 debug port. The PowerPC™ MPC565 embedded processor is Motorola’s latest highly integrated embedded microprocessor, designed principally for automotive applications such as engine and transmission control. The device allows external development, debug and calibration hardware to access the microprocessor “on-the-fly” without intrusion on program execution, to monitor or change variables, trace program flow or alter calibration tables through a debug port defined by IEEE-ISTO 5001-1999, the Nexus 5001 Forum’s global standard.
Developed as a cooperative effort by the membership of the Forum, a consortium of microprocessor and development tool vendors, IEEE-ISTO 5001™-1999 specifies an open, global, general-purpose interface for development, debugging and optimization of automotive systems. The Forum’s objectives are the development, dissemination, and implementation of a global interface standard for debugging of embedded processors.
Motorola has been an active participant in the Nexus 5001 Forum from its inception, and with its introduction of the MPC565 processor, the company has helped the Forum to reach a major milestone: Industry implementation.
“Motorola has supported the Nexus 5001 Forum for a long time and is very pleased to see the industry working together to provide the end user access to critical processor functionality without intrusion on the program’s execution,” said Ron Stence of Motorola’s Powertrain Systems Operation and a member of the Nexus 5001 Forum’s Steering Committee. “For the first time, real-time debug can be achieved with an industry standard debug and calibration interface.” Michael Healy of Ashling Microsystems Ltd., Limerick, Ireland, also a member of the Forum’s Steering Committee, agreed with Motorola’s assessments.
“Motorola’s introduction of their MPC565 automotive processor brings the objectives of the Nexus 5001 Forum to reality,” said Healy. “By basing the debug-strategy for their new microprocessor on IEEE-ISTO 5001-1999, Motorola has given a strong endorsement to this new global standard while ensuring that the new device is supported by powerful and effective debugging methods. Development-tool vendors and embedded-system designers can now create a powerful, uniform and re-usable development environment for this new microprocessor. In less than a year since first publication of the Nexus 5001 Forum standard, we’ve seen it progress from concept to real silicon.”
The Nexus consortium now includes more than 30 companies, spanning the semiconductor, development tools and automotive electronics industries. Although the initial focus of the consortium was on the stringent requirements of automotive powertrain applications, the overall goal is to see the general-purpose standard applied and adopted by all industries that will benefit, such as data communications and computer peripherals, wireless systems and other embedded control applications.
Administration services for the Nexus 5001 Forum and dissemination of IEEE-ISTO 5001-1999 are handled by the IEEE Industry Standards and Technology Organization (IEEE-ISTO). The IEEE-ISTO is a not-for-profit corporation that offers industry groups a wide range of support services within a flexible operational forum. The IEEE-ISTO provides an environment in which to develop standards and to facilitate activities that support the implementation of standards in the marketplace. The organization is affiliated with the IEEE (http://www.ieee.org) and the IEEE Standards Association (http://standards.ieee.org/).

Piscataway, NJ — 17 December 1999
The IEEE Industry Standards and Technology Organization (IEEE-ISTO) and the Nexus 5001 Forum™, a program of the IEEE-ISTO, today announced a significant milestone in their respective organizations, the availability of the IEEE-ISTO’s first Industry Group Standard. The standard, IEEE-ISTO 5001™ – 1999, the Nexus 5001 Forum™ Standard for a Global Embedded Processor Debug Interface, is now available for download from the Forum’s website at http://www.ieee-isto.org/Nexus5001/.
The Nexus 5001 Forum™ Standard is an open industry standard that provides a general-purpose interface for the software development and debug of embedded processors. The previous lack of a unified standard debug interface among the embedded processors on the market today has prevented software vendors from developing tools that can be used consistently across a broad range of processors.
“Completion of the Nexus 5001 Forum Standard is a significant step forward for developers of microprocessors and the tool developers who provide support,” said Arnold Berger, director of R&D, Applied Microsystems Corporation. “Unlike standard platforms, such as a PC, every embedded system is different, and the differences have been an ongoing obstacle for all suppliers to overcome. With an industry standard in place, we can focus on delivering value and innovation to our customers, and ultimately enable them to develop better products faster.”
Widespread adoption and implementation of 5001™ compliant processor architectures will result in toolsets being developed for use across microprocessor families from different manufacturers. This is expected to greatly improve the development, debug, qualification and tuning of embedded controller applications. Thus, standardization and implementation of this new interface will benefit customers’ choice and reuse of their 5001 compliant development tools on compliant processor architectures from different manufacturers. Methods and a process by which 5001 compliance can be validated is currently being defined to further support the global implementation goals of the organization. The IEEE-ISTO will play a key role in the rollout and administration of the future validation program.
“Motorola is working with the members of the Forum to advance the debug interface of embedded processors,” said Ron Stence, powertrain systems engineer, Motorola Transportation Systems Group.” The IEEE-ISTO is expected to ensure an open and verifiable real time debug interface standard for embedded processors and development tools across the industry. In addition, the advent of enhanced real time debugging is designed to improve the connectivity to the silicon, while reducing the development time with new and improved development tools across multiple architectures.”
Although the initial focus of the effort was based on the stringent requirements of the automotive powertrain applications, the goal is to develop a general purpose standard, encompassing all industries that will benefit from this standard interface such as data communications and computer peripherals, wireless systems and other embedded control applications.
