How Low Can 32 Bits Processors Go?

February 18. 2010 -- Moore’s Law observes that the number of transistors doubles for the same area every two years. The relentless fulfillment of this observation has been the rallying point for those who predict that 32-bit processors will replace 8-bit processors. The argument starts with the fact that the relative size difference between an 8- and a 32-bit-processor core approaches zero compared with the other resources on the chip as the transistor geometry continues to shrink. As the difference in the silicon area of 8- and 32-bit cores shrinks to nothing, 8-bit processors lose the price advantage that they once enjoyed. ... read more

Wireless To Go

February 4, 2010 -- As wireless technology becomes increasingly pervasive, vendors are offering a variety of hardware and software technologies to help you add communications functions to your products. Offerings support communications standards, including Bluetooth, Wi-Fi, GPS (global-positioning system), LTE (long-term evolution), and WiMax (worldwide interoperability for microwave access). Choosing the chips and associated software necessary to add wireless connectivity—and proving that your chosen implementation works and meets relevant certification requirements—can be challenging, however. Even if you put together a working design, you might not succeed in the market if you haven’t optimized performance, power consumption, cost, and size. And what’s optimum today might not be optimum as communications standards and your customers’ needs evolve, so you’ll want to choose a hardware and software implementation that lets you adapt without starting from scratch with each new generation (see sidebar “Wireless at a glance”). ... read more

The 36th Annual EDN Microprocessor/Microcontroller Directory

October 22, 2009 -- This directory aims to provide designers and system architects enough visibility into processor options to quickly narrow the list of candidate processors for each project. The vendor list on the left shows the companies selling software-programmable processors and cores and provides an overview for each as well as identifies the latest developments over the previous year at each company. The expanded online section presents each processor, with detailed information and block diagrams. The directory uses a common taxonomy for describing and categorizing target applications that helps you to quickly find and compare competing processors for your projects. You'll also find a listing of third-party-software-development companies. ... read more
