Low power update

Sunday, August 9th, 2009

Hi All,

  Sorry for the long hiatus. In fact, I wrote my introduction in June and then I was off on a vacation until last week. I just got back after spending some time in India. Even though this is my second trip to India in 2 years, I never got a chance to look closer at all the changes that have happened in India, before this trip. Man, I was quite amazed with the changes. For one, the rise of affluence amongst people was quite apparent. You can see it in the high rise buildings, number of cars, shopping malls, use of packaged goods, etc. This brings to an interesting perspective in terms of low power and power management. What I found was that wastage was also common amongst people. It seemed like the waste of goods and other products was directly proportional to the increase in personal wealth. Ans the most appalling thing was the rampant waste of energy. In all the places I visited, people did not care whether a light in a room was on or the fan was running, if no other people were around. It is predicted by a Mckinsey study that India’s electricity demand will be 3X what it is today by 2017 if the growth continues at a rate of 8% (this was the growth rate last year). I am sure, a big % of this consumption will be wasted anyway. The conservation has to be ingrained in the soceity in order to prevent this wastage. It is really important to strive for better approaches to promote conservation. Speaking of conservation, I recently looked at the Energy Star specification – One of the startling fact is the amount of energy consumed by “so called” external power supplies. These are the power adapters that we use for powering the laptop, telephone, music player, camcorder, etc. With a 30% power reduction in these devices, power savings can be greater than the power savings that can be achieved in all the data centers! Sequence Design Automation’s CEO, Vik Kulkarni, called this out in his newsletter column “Kulkarni Korner”  recently –

A big step in power management would be if someone can redesign the power supplies to make them power efficient. I heard that power efficiency was a prominent theme in this year’s DAC. Unfortunately, I did not attend DAC because of my trip to India. I had a chance to talk to Robert Smith, VP of Marketing, Magma before I went to India. I was curious to know the strategy behind Magma supporting Common Power Format in addition to the UPF support that they had announced earlier. Bob told me that customer requests were mainly the reason, but I could see a more confident Magma, listening and caring for its customers. Since then, Magma has released a number of announcements to get into multiple foundry reference flows. More later. Please feel free to express your comments.
