Kevin Kornher: Storage buffer that dynamically adjusts boundary between two storage areas when one area is full and the other has an empty data register. Texas Instruments Incorporated, Dwight N Holmbo, W James Brady III, Frederick J Telecky Jr, July 25, 2000: US06094695 (47 worldwide citation)

An electronic storage buffer (22) is efficiently used by dividing the buffer into a first (26) and second (28) storage area with a dynamically adjustable boundary (24) governing the respective sizes of each storage area. If the first storage area becomes full with data, the first storage area can be ...
