Abstract
A bit disposal apparatus includes a register (16) which is divided at a truncation point (14) into a left register segment (18) and a right register segment (28), wherein bits to be disposed of are contained in the right register segment. A decision mechanism initially examines the bits in the right register segment (28) and transmits a "1" signal (60) if and only if any of the bits in the right register segment is a "1". If any of the bits in the right register segment is a "1", a 1 is "jammed" into the least significant bit location (26a) of a result register (26a). A method of bit disposal includes the steps of setting a truncation point (14) in a register (16), thereby defining left (16) and right (28) register segments (54), loading a binary number into the register (56), examining the bits in the right register segment (58) and transmitting a right register signal which has a "1" value (60) if any of the bits in the right register segment is a "1", and replacing the least significant bit in a result register with a "1" if the right register signal has a "1" value (64).
