Abstract
The accuracy of data processing operations in an electronic device is improved through reductions in errors associated with data acquisition, reading, and transmission. In one embodiment, two or more modules of an integrated circuit are operated at different clock speeds and a voting scheme is utilized to obtain a valid data value from one of the modules. The disclosure describes methods, devices and systems that utilize the voting schemes to eliminate errors induced by race conditions in obtaining valid data values during data transfer by obtaining a plurality of data samples while the communicating modules are operating at the different clock speeds and selecting from among the data samples the valid data value.
