"Picture Logic" for "Bacchus" a Fourth-Generation Computer
L. A. Edelstein · The Computer Journal · 1963
This paper examines the logical problems involved in designing a proposed “picture arithmetic” computer (“Bacchus”) operating by transferring, inverting, shifting and superposing whole pictures of information, in parallel, simultaneously, without scanning. Each picture is controlled by a one-bit device of “third generation” hardware, and may contain up to 108 elements switched in as little as 10−8 seconds, and up to 104 pictures are possible. Associated problems such as input, output, and realization of this logic are considered in varying degrees of completeness. Serious heat problems will be met in the region 1017 to 1020 logical operations per second.
