FPGA Data scrubbing

scrubbing technique used reprogram fpga. can used periodically avoid accumulation of errors without need find 1 in configuration bitstream, simplifying design.

numerous approaches can taken respect scrubbing, reprogramming fpga partial reconfiguration. simplest method of scrubbing reprogram fpga @ periodic rate (typically 1/10 calculated upset rate). however, fpga not operational during reprogram time, on order of micro milliseconds. situations cannot tolerate type of interruption, partial reconfiguration available. technique allows fpga reprogrammed while still operational.
