Abstract
Aspects of the present disclosure provide techniques and apparatus for transferring data, such as between power domains via a first in, first out (FIFO) queue. An example method of transferring data includes selecting, via a source multiplexer, a first memory location included in a FIFO queue and storing first data, where the source multiplexer and the FIFO queue are in a first power domain; outputting the first data to a first level shifter; calculating, in the first power domain, a first value based on the first data; outputting the first value to a second level shifter; selecting, via at least one destination multiplexer included in a second power domain, the first level shifter and the second level shifter; calculating, in the second power domain, a second value based on the first data; and comparing the first value to the second value to generate a result.
