PACKED DATA MULTIPLYING-AND-ADDING DEVICE Russian patent published in 1999 - IPC

FIELD: computer engineering. SUBSTANCE: processor unit has first and second storage devices holding, respectively, first and second packed data. Each data pack includes first through fourth data items. Multiplying-and-adding circuit is coupled with first and second storage areas. This circuit incorporates first through fourth multipliers each receiving respective data. Multiplying-and-adding circuit also has first adder connected to first and second multipliers and second adder connected to third and fourth multipliers. Third storage area is coupled with adders and incorporates first and second fields for memorizing output data of first and second adders, respectively, as first and second data items of third data packs. EFFECT: improved efficiency with increased number of algorithms used. 37 cl, 48 dwg
