InvenSense Unveils Motion Processing Unit (MPU) for Smartphones
InvenSense announced the MPU-3000 family of motion processing units, featuring an embedded Digital Motion Processor (DMP) hardware accelerator engine. The DMP, together with an embedded FIFO, offloads high-frequency motion algorithm computation from the host application processor, reducing interrupts and host MIPS to improve overall system performance. It also provides a series of industry first features for complete motion processing in smartphones including the widest range of motions from 250 to over 2000 degrees/sec, built-in 16-bit ADCs, programmable digital filters, factory calibration to 1% sensitivity, built-in 6-axis sensor fusion, and 13mW of power consumption.
With a 4×4x0.9mm footprint and I2C or SPI digital interfaces, the MPU-3000 family is the first product of its kind to address handset requirements. The MPU-3000 extends the traditional inertial sensor architecture with the industry’s first embedded Digital Motion Processor (DMP). The MPU-3000 also integrates a secondary I2C interface to link an external accelerometer to the DMP, another first in the product category. This enables the DMP to perform 6-axis sensor fusion on output from the gyroscope and accelerometer and report quaternion output to the handset application processor, offloading the host from sensor timing synchronization and sensor fusion computation. Other features of the MPU-3000 include internal clock generation, an embedded temperature sensor, programmable interrupts, and an FSYNC pin for synchronizing image, video and GPS data.
“We have worked for the past several years to deliver a motion processing solution specific to the size, power and diverse application requirements of the handset market,” said Joseph Jiang, vice president of the handheld business unit at InvenSense. “The MPU-3000 family is a technological breakthrough that fully leverages our expertise in gyroscope and mixed-signal design, MEMS fabrication, and high volume test and calibration to deliver a truly unique solution to the market.”
The MPU-3000 family is available now for sampling by select qualified customers with mass production in Q2 2010.
