Abstract
A data processor for performing a division operation requiring shifting and the counting of the number of shifts, having no dedicated counters therefor. An additional shift left path from the temporary register of the previous bit to the next bit address bus is the only extra circuitry added, which greatly simplifies the shift left circuit of the temporary register. In addition, the dedicated counter may be eliminated as a formerly idle address incrementer circuit now performs the shift left and count functions. Not only are formerly idle registers now being used for lengthy shifting and cycle counting operations, but an overall savings in chip area is recognized, since the dedicated counter is eliminated and the dedicated shifter is greatly simplified.
