Application: Time-of-flight data processing device based on intelligence processing unit and data processing method (Patent ID: US20240045039A1)

The patent filed by MediaTek Inc. describes a data processing method for a time-of-flight data processing device. The method involves performing a conditional logical process and an image difference calculation by a vector calculating unit in an intelligence processing unit (IPU) based on sensing data from a time-of-flight ranging device to generate depth data. Subsequently, a filter process is carried out by a multiply-accumulate calculation unit in the IPU to generate output data. The IPU includes a vector calculating unit and a multiply-accumulate (MAC) calculation unit, with the former handling the conditional logical process and the latter managing the filter process.

Furthermore, the patent includes claims related to the specific operations and components of the time-of-flight data processing device. These claims detail the functions of the vector calculating unit, the MAC calculation unit, a look-up table (LUT) unit, and a central processing unit (CPU) in generating and processing depth data. The method also involves correcting data values, performing dot product operations, and utilizing transformation matrices to adjust resolution. Overall, the patent outlines a comprehensive approach to processing time-of-flight data efficiently and accurately using specialized units within the IPU.
