Editor's Note: Part 2, "Understand the considerations" is now available, click here.
In 2007, Gene Frantz
, Chau Mai
and Ivan Garcia
of Texas Instruments published a white paper in recognition of the fact that with ICs, we can no longer expect performance to naturally increase or power dissipation to decrease as readily as a function of the advances in process technology.
To quote the overview: “We need to find new ways to satisfy our continuing demand for more performance and to achieve that performance at a lower power level. By understanding the concepts of dependencies and guard bands, you can uncover hidden performance in your devices.”
We kick off this two-part series with that paper (click here to download PDF
). In it, the trio explain how performance and power dissipation depend on other variables under your control, as well as how IC manufacturers use guard bands to guarantee the performance of their products.
Armed with these details behind the datasheet specification, they show you how you can create the
product you need—even when the data sheet says it is impossible!
Of course, it’s not that simple. In Part 2
Frantz and Garcia will add to their original paper with some considerations you will need to understand if you attempt to use integrated circuits outside of the data sheet. Stay tuned. I should have it up later this week (week of Sept. 20th).
