Abstract:
1. A sensor polling unit for microprocessor integration, comprising: a sensor register model comprising one or more configuration logic blocks, each of the one or more configuration logic blocks being associated with an associated external sensor device of a plurality of external sensor devices; each configuration logic block being configured to issue a read command for one or more predetermined sensor data registers of the associated external sensor device in accordance with a read trigger supplied by a trigger generator of the configuration logic block, a global timer based on a clock signal of the microprocessor to supply a global time value to the trigger generators; and a polling state machine operatively coupled to the one or more configuration logic blocks for receipt of respective read commands therefrom, said polling state machine being configured to issue a corresponding read command to the external sensor device through a standardized bi-directional data communication interface connected to the associated external sensor device; wherein the polling state machine is further configured to receive register data transmitted by the external sensor device in response to the corresponding read command and transmit the received register data to a microprocessor accessible data memory area for storage.
