How I survived a Zune HD, and even came to like it
The Zune HD, Microsoft's latest answer to the popular Apple iPod, is a reasonable alternative to the iTouch player, but users need to be willing to climb what were for me some pretty steep and frustrating hurdles in setting up and figuring out how to use the Microsoft device.
Content transfer: Speed versus ease of use
The concept was to look at download speeds across three different interfaces--USB, WiFi and 3G--to compare and contrast the speed and ease of use. Three different cellphones were tested: iPhone 3G, BlackBerry Bold and BlackBerry Storm.
Video: B'com, Toshiba win sockets in iPhone 3GS
Teardowns of the third generation Apple iPhone reveal a more integrated—and probably lower cost--handset thanks in part to new design wins for Broadcom and Toshiba that caused one analyst to quip the 'S' in the iPhone 3GS may stand for savings.
USB OTG: The only wired interface portable consumer products need?
With so many portable product interfaces, UBS On-the-Go is perhaps the best choice in many situations
Spansion Methodologies of Optimizing Future Memory Systems
This paper discusses Spansion's methodology on estimating performance, namely, BW, power and latency of these future memory subsystems.
Implement a West Bridge for fast-changing mobile architectures
As internal and external memory evolves at a rate processors cannot keep up with, by using a West Bridge, mobile handset designers have access to fast-changing memory and peripheral technology, while offering low power consumption and system costs. Designers can mirror the success of the North and South Bridges of the PC architecture to drive the mobile handset market.
Use NAND Flash for cost, density and performance advantages for mobile handsets
This NAND flash tutorial covers recent trends, alternatives and even misconceptions regarding mobile handset storage subsystems that support multimedia features.
Mobile DDR spurs low-cost, low-power automotive electronics designs
In the memory unfriendly automotive environment, designers are having to seek out more and different system memory solutions. Here's one of the newest.
