The IMU-3000 is comprised of the following key blocks / functions:
5.3
The IMU-3000 consists of three independent vibratory MEMS rate gyroscopes, which detect rotation about
the X, Y, and Z axes. When the gyros are rotated about any of the sense axes, the Coriolis Effect causes a
vibration that is detected by a capacitive pickoff. The resulting signal is amplified, demodulated, and filtered
to produce a voltage that is proportional to the angular rate. This voltage is digitized using individual on-chip
16-bit Analog-to-Digital Converters (ADCs) to sample each axis. The full-scale range of the gyro sensors
may be digitally programmed to ±250, ±500, ±1000, or ±2000 degrees per second (dps). ADC sample rate is
programmable from 8,000 samples per second, down to 3.9 samples per second, and user-selectable low-
pass filters enable a wide range of cut-off frequencies.
5.4
The embedded Digital Motion Processor (DMP) is located within the IMU-3000 and offloads computation of
motion processing algorithms from the host processor. The DMP acquires and processes data from the on-
