Abstract
A method and system to a system to provide a sensor data to a host device is disclosed. The system includes a first clock generator that generates a first clock. The system also includes a second clock generator that generates a second clock. The sensor data is sampled based on the first clock. The sensor data is presented to the host device, based on the second clock.
Claims30
A method for providing a sensor data to a host device, comprising:
- providing a motion processing unit with a first clock generator and a sensor, the first clock generator generating a first clock;
- providing a second clock generator in the host device, the second clock generator generating a second clock;
- sampling the sensor data based on the first clock, the sensor data sampled in the motion processing unit based on the first clock ahead of the second clock, sensor data presented to the host device based on the second clock;
- modifying the sampled sensor data based on the first clock to generate a projected sensor data by the motion processing unit, the projected sensor data indicative of a likely future sensor data at the time of presenting the sensor data to the host device, based on the second clock, projected sensor data generated based on a time difference between the first clock and the second clock, wherein the time difference indicates how much time the second clock is ahead in future from the first clock used to sample the sensor data;
- and
- presenting the generated projected sensor data indicative of the likely sensor data at the time of presenting the sensor data to the host device based on the second clock.

A system to provide a sensor data to a host device, comprising:
- a motion processing unit with a first clock generator and a sensor, the first clock generator configured to generate a first clock;
- a second clock generator in the host device, the second clock generator configured to generate a second clock;
- the sensor data sampled from the sensor, based on the first clock;
- the sampled sensor data based on the first clock modified by the motion processing unit to generate a projected sensor data, the projected sensor data indicative of a likely future sensor data at the time of presentation of the sensor data to the host device, based on the second clock, projected sensor data generated based on a time difference between the first clock and the second clock, wherein the time difference indicates how much time the second clock is ahead in future from the first clock used to sample the sensor data;
- and
- the generated projected sensor data indicative of the likely sensor data at the time of presentation of the sensor data is presented by the motion processing unit to the host device based on the second clock.
