ABSTRACT:
An expandable scaler for scaling an N bit digital word. The system comprises first and second scalers each of which comprises N input terminals for receiving an N bit word, N output terminals, and (x+1) corresponding groups of first switching logic to form (x+1) corresponding pairs of groups of first switching logic with each group having input terminals and output terminals and being arranged in successive manner with the output of each of the first (x) groups being connected in parallel manner to the input terminals of the next successive group and where 2.sup.x =N, and leads for supplying the N bit digital input word to the input terminals of the group of first switching logic and further with each pair of corresponding groups of switching logic means responsive to an enabling signal to selectively shift the N bit digital input word by one of 2.sup.o, 2.sup.1,-2.sup.x =m bit positions. Also provided are (x+1) groups of second switching logic which are individually responsive, when enabled, to corresponding ones of the (x+1) groups of first switching logic, when enabled, of said first and second scalers to connect the R least significant bits of the N bit digital input word supplied to the group of first switching logic of the first scaler to the R most significant bit positions of the corresponding group of first switching logic of the second scaler. The system is expandable in word length by added pairs of scalers corresponding to the first and second scalers and substantially in parallel therewith and expandable in bit shifting capability by adding similar scalers to the outputs of scaler pairs.
