Abstract: A method and system are described for data acquisition between or among two or more systems having individual clock domains, such as from a sensor system to a processor system, each system operating on its own clock domain. The sensor system, such as navigation sensors, generally output time information via various discrete signals that are generated by a clock of the sensor system. On the other hand, the processor system, such as an FPGA, may operate on a different clock. The FPGA may use predicted windows in which to monitor for the availability of sensor data, which will be timestamped for a navigation algorithm to subsequently use. Use of such predicted windows can filter unwanted data transactions, which may arise from various glitches or mis-timings between the two systems.
