Hurry Up and Get Idle

I was talking this week with Jim Handy, a widely recognized semiconductor analyst with Objective Analysis. We were discussing how common wisdom suggests that performance often comes with the added cost of increased power and inefficiency. A fast car is going to burn more gas. The quickest processor is going to consumer more watts of energy. It is often true.

I mentioned to Jim that our assumption was that Energy Star appliances and equipment, which many of our customers produce, would require low power memory devices. But a customer informed me that, on the contrary, they want us to provide them with the highest performance memory solutions. High performance lets them provide their customers with an “instant on” user experience when they initiate a task on equipment that is in a “deep sleep” mode.

This is counterintuitive, but the fact is, that low power consumption is achieved by putting equipment into deep sleep mode and our high performance NOR Flash memory is critical in enabling that “instant on” experience for users.

Jim reminded me of an Intel axiom called “HUGI”. It stands for Hurry Up and Get Idle. Sometimes it is actually more efficient to perform a task as quickly as possible so you can return to a state of no or low power consumption. The extra power you use during that short spike can result in an overall power savings because you were able get idle again more quickly.

Conventional wisdom doesn’t always prove to be right. You really need to understand your environment to know what’s most important to your customer and how you can differentiate from your competition by giving customers the ability to build a better end product.

TFT Clusters Demand for High Density NOR

Today’s innovations in automobile design result from the growing demand for more electronics within the car. Cars now come with state-of-the-art audio and video systems, high-tech and graphic-rich navigation systems, and wireless technologies for many types of communications.

Safety electronics is on the cusp of making a quantum leap forward with advanced driver assistance systems (ADASs), which are involved with braking, steering, and collision avoidance. When drivers become distracted, the risk of an accident quickly increases. In 2008 alone, according to the National Highway Traffic Safety Administration (NHTSA), 6000 Americans died due to a distracted driver and another 500,000 were injured.

Automakers are now turning their attention to accident prevention, with a focus on improving the driver’s experience. To lessen distractions, key vehicle and driving information needs to be displayed in front of the driver, specifically in the dashboard.

The instrument cluster, a space once reserved for electromechanical gauges and light indictors, is transforming into a new digital information center for drivers. Thanks to the advancement and maturing reliability of digital thin-film-transistor (TFT) displays, improved signal processing power, and high-speed digital communication, analog-based systems are rapidly migrating to digital system displays.

Today’s dashboards built around TFT displays still provide basic vehicle information, such as drive train position, speed, fuel levels, and engine status, while bringing in additional data from outside the car. This added information comes from new innovations like 360° cameras, night vision, lane-departure warning, blind-spot detection, and 3D graphic navigation data.

Digital clusters enable a more cost-effective and flexible means to converge all vehicle and safety information, which further minimizes any unnecessary distractions. The driver no longer needs to look down or fumble with the center console searching for music, make phone calls, look up driving directions, or turn one’s head to look at a blind spot.

While these new advances offer many new and exciting options, they also require designers to find innovative solutions to control costs as well as deliver critical performance capabilities and ensure long-term product reliability. Spansion’s NOR Flash is the ideal solution to meet system designer’s requirement for performance, reliability, and cost. The following article provides a nice overview.
