This article refers to the address: http://

The MPU-9150 is the world's first nine-axis motion tracking (MotionTracking) component designed for consumer electronics devices such as smart phones, tablet computers, and wearable sensors that require low power, low cost, and high performance. .

The MPU-9150 includes InvenSense's motion-sensing fusion calculation (MotionFusion) and run-time calibration firmware, which allows manufacturers of motion-sensing products to eliminate the need to select, test, and integrate in the system phase. The cost and trouble of each component is ensured, and its sensor fusion algorithms and calibration procedures are guaranteed to provide optimal performance for the consumer.

The motion sensing human interface has quickly become a key feature of many consumer electronics products such as smart phones, tablet computers, game consoles, and smart TVs. Ability to track actions in free space, transform actions into input commands, and enable consumers to intuitively interact with their electronic products.

The MPU-9150 includes motion-sensing fusion calculus and operational calibration firmware that allows manufacturers of consumer electronics to commercialize cost-effective motion-based functionality.

The MPU-9150 is a system-in-package (SiP: System in Package) product that integrates two chips: an MPU-6050, a three-axis gyroscope, a three-axis accelerator, and a built-in complex nine-axis motion sensing fusion The algorithm's digital motion sensing processor (DMP: Digital Motion Processor); the other is the AK8975, which is a three-axis digital electronic compass. The nine-axis motion sensing fusion algorithm included in the MPU-9150 connects all internal sensors to collect the entire set of sensing data. Available in a 4x4x1mm LGA package, this product is a compatible upgrade to the MPU-6050 integrated six-axis motion sensing tracking component, providing a simple upgrade path for easy installation on space-constrained boards.

The MPU-9150's InvenSense motion sensing application (MotionApps) platform eliminates the motion-based complexities of motion-sensing products, reduces the load on the operating system when managing sensors, and provides application development. A structured set of APIs.

In order to accurately track fast and slow motions, the gyroscope's user-programmable full-scale range is Â±250, Â±500, Â±1000, Â± At 2000Â°/sec (dps), the programmable full-range sensing range of the accelerator is Â±2g, Â±4g, Â±8g, Â±16g, and the full-frame sensing range of the electronic compass is Â±1200Î¼T.

Fuwei Group's agent production line Leadcore launches LC1810 dual-core chip solution

Fuwei Group's agent production line Leadcore launched the high-performance dual-core Cortex A9 smartphone platform LC1810. The LC1810 prototype has surpassed the current mainstream dual-core A9 smartphone in terms of performance indicators such as CPU and GPU. The solution synchronizes output to the LCD TV through the HDMI interface, and plays multiple audio and video movies in high-definition. The LCD screen presents the viewer with the perfect visual experience with the highest resolution of 1080P. At the same time, the dual-core Mali400 3D processing unit is growing for large games, and many large games are running smoothly. The LC1810 also supports dual-camera 3D camera and 20 million ISP HD camera, which is very exciting.

The maturity of the LC1810 chip will contribute to the popularity of dual-core smart phones in the TD-SCDMA market. At present, more than ten terminal manufacturers based on the Lianxin 1810 chip platform and a number of mobile phone terminals of IDH manufacturers are in the process of intensive R&D and testing. The first model of Alpha customers has been launched, and it is expected that in the fourth quarter of this year, More than 10 LC1810-based TD-SCDMA smartphones will be available commercially.
