    摘要: A differential signal driver includes a pre-driver configured to generate a constant charging current and a constant discharging current. A first capacitor of the pre-driver is charged with the charging current when a differential input signal has a first state, and discharged with the discharging current when the differential input signal has a second state, thereby developing a first output control voltage on the first capacitor. A second capacitor of the pre-driver is discharged with the discharging charging current when the differential input signal has the first state, and charged with the charging current when the differential input signal has the second state, thereby developing a second output control voltage on the second capacitor. An output driver circuit generates a differential output signal in response to the first and second output control voltages. The slew rate of the differential output signal is controlled by the charging and discharging currents.

    摘要: This disclosure describes systems, methods, and devices related to enhanced validation of video codecs. A device may receive validation results for a video codec using a first computer programming language, the validation results indicative of invocations of functions and conditions of the code; identify, from the validation results, a first validation test that invoked a first function or condition of the code; identify, from the validation results, a second validation test that invoked the first function or condition of the code; determine, from the validation results, that the first validation test and the second validation test overlap in invoking the first function or condition of the code using the first computer programming language; and generate, based on the overlap, a first subset of the validation tests with which to validate code of the video codec using a second computer programming language.
