ABSTRACT:
The times-two (.times.2) through times-nine (.times.9) multiples of a supplied multi-digit BCD number are produced using one machine cycle for performing a set-up operation and thereafter one additional machine cycle for producing all the .times.2-.times.9 multiples. A multiples generating circuit in accordance with the invention comprises: (a) an operand-storing register (OSR); (b) a multiple-storing register (MSR); (c) a multiplexer having a first input coupled to the output of the operand-storing register (OSR) and a second input coupled to the output of the multiple-storing register (MSR); (d) a .times.3 unit having an input coupled to the output of the multiplexer and an output coupled to the input of the MSR; (e) a first .times.2 unit having an input coupled to the output of the OSR; (f) a second .times.2 unit having an input coupled to the output of the first .times.2 unit; (g) a third .times.2 unit having an input coupled to the output of the second .times.2 unit; (h) a fourth .times.2 unit having an input coupled to the output of the MSR; (i) a .times.5 unit having an input coupled to the output of the OSR; and (j) a .times.7 unit having an input coupled to the output of the OSR.
