The inclusion of two discrete accelerometers /4/initially seem odd, given the extra room and cost needed
iPhone 6 And iPhone 6 Plus Include Two Built-In Accelerometers
Apple has equipped its recently announced iPhone 6 and iPhone 6 Plus with two accelerometers. This revelation came after the phone’s teardown by Chipworks. A three-axis Bosch BMA280 accelerometer was spotted inside the phones in addition to InvenSense called the MPU-6700. You might be wondering why Apple went to such efforts in order to have two accelerometer but it all makes sense to the company.
As indicated by Chipworks, the InvenSense part offers an entire host of capacities, and has the capacity work in a mixed bag of distinctive modes. This takes on at the expense of force utilization however, which is the place the less complex part from Bosch becomes possibly the most important factor. The additional force draw comes somewhat from the Invensense’s enhanced affectability of 16684 LSB/g – a potent increment over the 4096 of Bosch’s offering.
It’s set that the reason Apple has incorporated the two focuses is basically down to that power utilization, and the additional time required by the Invensense movement sensor when its obliged to begin cool. Taking 30ms to get going /4/not sound like quite a while, yet when contrasted with the 3ms of the Bosch, it’s an unfathomable length of time. Chipworks accepts that the Bosch unit will be utilized by iOS when affectability is not obliged however speed would be gainful.
In light of that, basic errands, for example, going about as a turn sensor for the iphone’s screen would be superbly suited to Bosch’s lower power utilization, with more exceptional work being tackled by the Invensense MPU-6500. This obviously means games, for instance.
