Distinguished lecture: IEEE CAS DLP talk - CAS Chapter Bangalore
IEEE circuits and Systems Society Chapter at Bangalore cordially invites you to a distinguished lecture under the DLP by
Speaker: Dr. Hubert Harrer, IBM Deutschland Research & Development GmbH, Stuttgart, RB 243294
Topic: System packaging and technologies of IBM´s latest system z high end servers
Date: 4th November 2008
Time: 11.00AM
Venue: CEDT Conference Hall, I.I.Sc, Bangalore

Abstract: The presentation compares the system packaging and technologies of IBM´s latest system z high end servers. Starting from the z900, the system design change towards a blade-like architecture will be explained. The latest system generation z10 has achieved a doubling of the multiprocessor performance compared to the z9 system by maximizing its CPU configuration in combination with increasing the speed of the interconnections. The heart of a processor node consists always of a multi chip module (MCM) which contains the double core processor chip, the cache chips and the bus adaptors to the memory and the IO chips. This MCM technology is the key for the high bandwidths between processor chips and the cache chips. The glass ceramic module has accomplished this challenge within the 102 layers resulting in a total wiring length of 545m. The increase of bandwidth requirements for the packaging will be compared for the last generations. Also the complex board and card technology of the second level packaging will be discussed.

The cooling of the system is being done with a modular refrigeration unit (MRU), which cools the processor chips down to 45-55C. This low temperature ensures highest reliability and reduced leakage current of the chips. An air cooled backup mode at a lower frequency ensures that the system does not go down in case of an MRU fail. The MCM has been designed for a maximum power of 1650W.
The presentation will focus on the electrical design methodologies for high end servers like power delivery concepts, signal integrity methodologies and power integrity designs for delivering such high currents.

About the speaker: Dr. Harrer is a Senior Technical Staff Member (STSM) since 2002 working in the IBM Server and Technology Group. He received his Dipl.-Ing. degree in 1989 and his Ph.D. degree in 1992 from the Technical University of Munich. In 1993 he received a DFG research grant to work at the University of California at Berkeley in the paradigm of Cellular Neural Networks. Since 1994 he has worked for IBM in the Boeblingen Packaging Department. In 1999 he was on international assignment at IBM Poughkeepsie, New York.

He was leading the z900 MCM designs and is the technical lead for z-series CEC packaging designs since 2001. This includes the system z990, z9 and system z10 mainframe computers. His technical interests focus on packaging technology, high frequency designs and electrical analysis for first and second level packaging. He has published multiple papers and holds 7 patents in the area of packaging.

Seminar on Lo3: Low-power, Low-cost, Local Voice and Messaging for Rural Regions
PragaTI (TI India Technical University) and IEEE Circuits and Systems Society Bangalore Chapter jointly announce a seminar
Speaker: Prof. Bhaskaran Raman (IIT Bombay)
Date: 26th June, 2008 (Thursday)
Time: 3.00 pm – 4.00 pm
Venue: F-1, TI Bangalore Office

Everyone is welcome to attend! Please RSVP to, and arrive at least 15 minutes prior to the seminar to go through security formalities.

Abstract: Two metrics of prime importance in system design for rural deployment are: system cost and power consumption. In this work, we propose a novel approach for building a local communication system, within a village. Our approach is based on the use of IEEE 802.15.4 as the underlying technology. Although designed for a completely different application space, and although the radio capacity is small, we argue that 802.15.4 is ideally suited to minimize cost as well as power consumption. It is possible to enable a whole suite of useful applications based on voice as well as text. The use of the radio in this non-traditional setting brings up several technical challenges however. This talk articulates the motivation behind this system, and the various research challenges as well.

About the speaker: Bhaskaran Raman received his B.Tech in Computer Science and Engineering from Indian Institute of Technology, Madras in May 1997. He received his M.S. and Ph.D. in Computer Science from University of California, Berkeley, in 1999 and 2002 respectively.

Seminar on Bluetooth & WLAN Solution Architectures
IEEE Circuits and Systems Society Bangalore Chapter, in association with PragaTI (TI India Technical University) announces a seminar
Speaker: Bhartendu Sinha (Texas Instruments)
Date: 24th June 2008
Time: 10:00AM - 11:30AM
Venue: TR-1, Texas Instruments India, Bagmane Tech Park, CV Raman Nagar, Bengaluru, 560093

Those who wish to attend should RSVP to before June 17, 2008 and arrive at least 10 minutes before the seminar begins.

Abstract: Wireless technologies are increasingly become pervasive. Designs from ‘non-wireless’ industries typically do not have adequate wireless technology expertise. Yet these designers are seeing their firms request them to incorporate wireless interfaces in their current and future products. This results in multiple technical challenges for such designers – which they often become aware of too late, i.e. after a new product initiative fails to deliver. This presentation provides guidelines on how to choose solution architectures for two of the most prevalent consumer wireless technologies today – Bluetooth and WLAN. It also advises designers on how to choose wireless technologies and how to leverage appropriate partner networks for the design and manufacture of products with wireless interfaces.

Objectives: To expose designers to the key selection parameters, industry available solutions, and design success factors for incorporating Bluetooth / WLAN into products designs.

Target Audience: Software, hardware and system designers, who are using or planning to use either Bluetooth or WLAN in their product designs.

Abstract: The National Technology Roadmap for Semiconductors and the International Technology Roadmap for Semiconductors together define the general characteristics of semiconductor technology progression for the next 15 years. In this talk, we the applicability of roadmapping to other industries. After a brief historical perspective on the evolution of the roadmaps, the talk will dwell on the conditions that led to the success of the roadmapping technique in the semiconductor area. First, roadmaps must be developed through a consensus of the industry to which they apply, and individual companies must be willing and able to share their knowledge of the technology needs. The participating companies must provide, on a continuing basis, the time and talents of employees in advising, reviewing, and critiquing the technology efforts, and in maintaining the roadmap.

It is equally important to look at the technological needs of university research laboratories and independent research institutes. Governments must participate and encourage the cooperative roadmap activity. The talk is intended for participants from industrial bodies, universities, and governmental organizations.

    Seminar on Residue Number Systems-Review of Recent work

    IEEE CAS Bangalore Chapter announces a seminar
    Speaker: P.V. Ananda Mohan (Executive Director, ECIL, Bangalore)
    Date: March 6, 2008
    Time: 3.00 – 4.30 PM
    Venue: TI Bangalore Auditorium

    Please RSVP to and arrive at TI reception by 2.45 pm to be escorted to the room.

    Abstract: The advantages of RNS over conventional number systems is that several smaller word length processors can be used to work in parallel to realize signal processing operations as against processing using a single large word length processor.
    The problem, however, with RNS  based DSP is that there is a need for front end conversion from conventional number to residue form and vice versa. Moreover, the operations such as sign detection, comparison and scaling are more involved in RNS. As such, research has been on the choice of powers of two related moduli sets  where moduli are of the form 2x or 2x±1. Several three, four and five moduli sets have been investigated. In this lecture we address the topics of Binary to RNS conversion, RNS to Binary conversion for these specific moduli sets, Area-time trade-offs, modulo adders, modulo multipliers. Some new theorems such s ART are also introduced.  Application of RNS to complicated problems such as exponentiation needed in RSA are also considered.
