Electronic circuits based on AVR microcontrollers Texas Instruments Showcases OMAP 5 GPU Capabilities with GLBenchmark 2.5 In February, Texas Instruments compared the browser rendering performance of its OMAP 5 platform to the Nvidia Tegra 3, and the benchmark results showed OMAP 5 was twice as fast @ 800 MHz than the Tegra 3 @ 1.3 GHz. Today, they’ve uploaded a video showing the 3D performance a tablet based on OMAP 5 (and PowerVR SGX 544-MP GPU) against a market-leading tablet (I guess it’s the Apple iPad 3 with PowerVR SGX 543 GPU) using GLBenchmark 2.5 with the following setup: 1080p resolution.On-screen and off-screen tests were conducted to compensate for the “Vysnc Limited” scenarios.(24bpp) 16bit depth tests to better represent high-end game contentPower saving mode disabled and device connected to a power source.No background tasks and airplane mode “on.” GLBenchmark 2.5 Offscreen Results The on-screen results show 38 fps for the OMAP 5 vs 34 fps for the other platform, or a 12% performance boost.

Driver para motores a paso AVR Stepper Motor driver #atmel Pues como les dije me desde hace tiempo tengo mi librería de AVR´s aun es muy básica la tengo en google code la pagina es hace tiempo que no subía algo ahí y pues esta vez subí un control para motores a paso en un AVR, este controla 2 motores a paso bipolares, viene incluido el código y el diagrama esquemático es pero el fin de semana hacer una prueba lo malo es que ahorita aquí en el DF no tengo motores a pasos y ando medio corto de dinero y pues no creo comprar uno aparte traigo mas cosillas pues les explico un poco sobre los motores a paso o motores Paso a paso. Aunque creo ya lo había explicado antes esta vez tratare de explicarles un poco mas Básicamente hay dos tipos de motores a pasos, unipolares y bipolares, ambos tienen 2 bobinas. Motores a pasos Bipolares Figura 1 Motor a pasos Bipolar de 2 bobinas. Figura 2 Puente H Tabla 1 Secuencia de activación de las bobinas
NVIDIA: OMAP 4470 is 50% faster than Tegra 3 | Tech News Pedia Yesterday Amazon announced its new Kindle Fire HD soc based on the Texas Instruments OMAP 4470 , which claim has outperformed its competitors products based on Nvidia Tegra 3 SoC . Comment could not be left without a response from Nvidia: It’s good to see companies continue to use a Tegra 3 as the standard to compare their products. The popular Nexus 7 showed the capabilities of the Tegra 3 processor. You can not measure the experience that provide the user with comparisons (benchmarks) synthetic. At other times, companies with products based on the arm Cortex-A15 architecture as Snapdragon S4 Series (based on Qualcomm’s Krait architecture), OMAP 5 Texas Instruments and Exynos 5 of Samsung, have proclaimed their superiority to Tegra 3, which architecture is based on the Cortex-A9, but very few companies with products that claim Cortex-A9 also be higher, as the SoC K3V2 of Huawei.

lams_007 : Nuevos jugetes new toys #Atmel... OMAP 4470 faster than Tegra 3, claims Amazon CEO Jeff Bezos outlines the difference Yesterday Amazon CEO Jeff Bezos revealed three new Kindle tablets, including 7- and 8.9-inch Kindle Fire HD tablets, and he briefly mentioned that the great processor and graphics engine behind both tablets comes courtesy Texas Instruments. The 8.9-incher uses the OMAP 4470, while the Kindle Fire HD is apparently based on the OMAP 4460, with slower graphics. Last time we checked the OMAP 4470 was a 45nm dual A9 core that works somewhere between 1.5GHz and 1.8GHz, comes with hardware accelerated 2D and 3D and supports 1080p in both 2D and 3D video. The graphics core of choice is a PowerVR SGX544, clocked at 384MHz and a dual channel 32bt 466MHz LPDDR2 memory support. The OMAP 4460 features SGX 540 graphics. According to Jeff Bezos the new Kindle Fire HD and Texas instrument OMAP 4470 can do 12 billion floating point operations per second while Tegra 3 can do only 8 billion, claiming that OMAP 4470 can do 50 percent more.
Nest Teardown Awhile ago I read about Nest, a newfangled thermostat with a color display and some interesting ‘learning’ techniques for keeping your home warmed or cooled, as sensible as possible. Did I mention the beast has IR proximity, PIR movement, humidity, magneto scroll, and a mini USB connector? Oh. It does. It’s kind of awesome, but it comes at a price. Hi Matt, This offer is a great idea! From your friends at SparkFun,-Nathan Much to my surprise and honor, I got a response from Matt: Thanks for the note Nathan! No way! Disclosure time: We didn’t get Nest for free. After tearing apart the Nest then re-assembling, it actually continued to function (a first for me!).
