Abstract
A gaze point calculation apparatus includes: a first cache register, a multiplexer, an arithmetic unit assembly, and a state machine. The first cache register is configured to receive and store first coordinates and a plurality of calibration parameters required when second required are obtained through calculation according to the first coordinates. The state machine is configured to control the multiplexer to select each time at least one value from the first cache register and transmit same to the arithmetic unit assembly. The arithmetic unit assembly is configured to perform a preset operation on the at least one value received each time until the second coordinates are obtained, and output the second coordinates under control of the state machine.
