Abstract
A programmable bubble material arrangement employing a plurality of logic components for performing eight different possible logic and arithmetic operations on two applied serial digital data streams. Separately applied control signals in the form of bubbles are applied to the arrangement to selectively program the arrangement, as desired. The logic components include transient bubble switches, resident bubble switches, bubble generators, bubble annihilators, exclusive merge elements, disjoint crossover elements and delay elements. The operations selectively performed are: A + B, A .sym. B, AB, A plus B with carry, A + B, A .sym. B, AB, and A plus B with carry. The arrangement operates equally with data streams either loosely packed (data bubbles periodically placed in the stream) or tightly packed.
