아이폰 6에는 가속도계가 2개 들어가 있다고 목적은 배터리 사용량을 줄이고, 사용자 경험을 향상시키기 위해서. 민감하지만 전력소비가 좀 있는 6축짜리가 한개, 덜 민감하지만 전력소…

Quite a bit of chatter is bubbling up over the new iPhone's accelerometers, speculating why it has two of them. At Chipworks, where we reverse-engineer semiconductors, it's our job to get to the bottom of such things. Here's a blog I posted recently comparing the accelerometers. Although the blog is already posted on Chipworks -- and I encourage you to read our full iPhone teardown -- I'm posting it here on EE Times to get your comments. * * * The iPhone 6 contains a six-axis InvenSense combination gyroscope-accelerometer and a Bosch BMA280 three-axis accelerometer. There has been some considerable debate in the blogosphere as to why Apple might have incorporated the extra accelerometer functionality. We speculate that the two devices are incorporated to improve the overall user experience, while minimizing power consumption. We believe the InvenSense device to be the MPU-...
