Abstract:
1. A calibration system, comprising: a data processing apparatus, for converting a test pattern into a test output according to a test firmware trim value received under a calibration mode, and for converting a non-test pattern to a non-test output according to a target firmware trim value stored therein under a normal mode, wherein the test output is an analog signal; and a calibration apparatus, coupled to the data processing device, for calibrating the data processing apparatus, the calibration apparatus analyzing the test output to tune the test firmware trim value outputted to the data processing device, and for controlling the data processing device to store a specific test firmware trim value as the target firmware trim value when an analysis result of the test output generated in reference to the specific test firmware trim value indicates that a predetermined criterion is met, the calibration apparatus comprising:
