Dubbed Denver, the processor will be used in the firm’s first 64-bit version of its Tigra K1 mobile processor designed for Android smartphones and tablets. This new version of Tegra K1 pairs our 192-core Kepler architecture-based GPU with the 64-bit, dual-core CPU. Each of the Denver cores implements a 7-way superscalar microarchitecture (up to 7 concurrent micro-ops can […]

Over the years, demand for efficient, light, fast-charging, safe, and cost-effective portable power has led to development of many new battery technologies, including nickel-metal hydride (NiMH), rechargeable alkaline, lithium-ion (Li-ion), and lithium-polymer (Li-poly), to name a few. Generally speaking, these new battery chemistries require more sophisticated charging and protection circuitry to maximize performance and ensure

Intel may have grabbed the headlines with the announcement that its first 14nm processor will be on general release next year. But by then the Broadwell processor will just one of a number of 14nm chips in production. Intel has long insisted that its production capability, which it has always invested in to keep at
What’s new about 14nm processors for Intel? Continue Reading
On his blog, Miguel presents one of his latest projects: This project shows the operation of an RGB lamp using a digital LED strip. After activating the bluetooth connection, the user can open the GUI on the PC to control the lamp. The program shows a hue palette divided into 30 rods, one for each LED of
An Arduino-controlled RGB lamp Continue Reading
The MEMS (microelectromechanical system) market is starting to motor. It grew at just over 10% last year and is likely to grow even faster this year. This is good news for the ‘newest’ semiconductor device market. But can it continue to grow at this rate? Market analyst Yole Développement has already warned of price pressures pegging back
MEMS sound great, but can it last? Continue Reading
A couple weeks ago I received some sample products from Dorji Applied Technologies, a china-based company that make varieties of RF and sensor modules. One of the products I received was their latest DSTH01 sensor module that carries Silicon Labs’ Si7005 digital relative humidity and temperature sensor on board. Things I liked about it are it is inexpensive

Interest in triple-level cell (TLC) NAND flash is growing and the high density flash memory technology could have cost benefits over single-level NAND in SSDs, but only if endurance and retention questions marks are addressed. For US-based NAND flash controller supplier Silicon Motion Technology the answer is increased error detection in the flash controller. It has employed three levels of
TLC NAND flash gets error correction it needs to takeoff Continue Reading
My son got one of these Leap Frog toys a few years ago as a gift. He enjoys playing with it very much. I am not sure how much counting and learning he is doing but it makes funny noises and sings to him so its a lot of fun. Recently the unthinkable happened. It

Two-dimensional (2D) materials such as molybdenum-disulfide (MoS2) are attracting much attention for future electronic and photonic applications ranging from high-performance computing to flexible and pervasive sensors and optoelectronics. But in order for their promise to be realized, scientists need to understand how the performance of devices made with 2D materials is affected by different kinds
In my previous post, I showed my design of a dual tracking ±30V linear power supply. My goal was to use the transformer (28V+28V, center tapped) from an old Deltron W127G open-frame power supply and build a lab supply that can be digitally adjusted in both constant voltage and constant current modes. I also wanted
