Abstract
In a microprogrammed data processing system, the throughput of the system is increased during the processing of decimal numeric instructions by apparatus which is conditioned by the instruction descriptors in advance of receiving the operands to align the decimal digits of the operand words as the words are received by the apparatus from memory. The descriptor information for each operand includes the scale factor, the position of the sign, the position of the most significant character within the word, whether it is a floating point or scaled operand, the number of bits in each decimal character, either 4 or 9 bits, and the length of the operand. The apparatus is conditioned by the descriptor information to align the two operands for processing.
