Abstract: A lookup table structure having multiple lookup tables is configured to include a quaternary adder. In particular examples, an adaptive logic module (ALM) including a fracturable lookup table (LUT) is configured to include a quaternary (4-1) adder. In some examples, only an XOR gate, an AND gate, two single bit 2-1 multiplexers, and minor connectivity changes to a LUT structure supporting a ternary (3-1) adder are needed to support 4-1 adders. Binary (2-1) and ternary adders are still supported using the original signal flows, as the ternary adder feature can be easily multiplexed out.

Abstract: An information processing device includes: an interface to/from which a recording medium is attachable/detachable; a data storage device that stores data; a data extractor that extracts data recorded on the recording medium connected through the interface, with the data maintained in a data configuration of the recording medium; and a controller that controls the data storage device to store the data extracted by the data extractor together with an identifier which specifies the recording medium, with the data maintained in the data configuration extracted.
