DEVICE FOR CALCULATION OF ABSOLUTE VALUE OF M- DIMENSIONAL VECTOR Russian patent published in 1997 - IPC

FIELD: computer engineering. SUBSTANCE: device has sign decoders $$$, first group of adders- subtracters $$$, second group of adders-subtracters $$$, shift registers $$$, sign alternation unit 5, registers $$$, group of adders $$$, group of shift registers $$$. Device provides conversion of vector components in m-dimensional space during single operation by means of orthogonal reflection transforms without long multiplication. This results in possibility to increase speed by o(n) additions for single iteration and by o(n2) additions for pipe-lined processing using n devices which are connected in series. EFFECT: increased speed. 3 dwg
