Abstract
A loop controller for a fiber optic gyroscope employs distributed data processing to compress numerous additional useful functions into each loop transit time. The architecture of the loop controller includes a field programmable gate array for generating variables of varying sign. In addition, the array acts to buffer the transmission of parameters between the gyro processor and an auxiliary processor. The auxiliary processor updates such parameters (which do not require updating every loop transit time) and a number of such parameters are multiplied by values generated by the array in operations performed by the gyro processor that replace what would otherwise require throughput intensive test and branch operations. The combination of the off-loading of selected variable and parameter generation and updating with programming of the gyro processor for parallel processing permits the loop controller to perform numerous useful operations not previously possible during a realistic loop transit time.
