Abstract
The invention set forth herein describes a mechanism for efficiently performing extended precision operations on multi-word source operands. Corresponding data words of the source operands are processed together via each instruction of a cascading sequence of instructions. State information generated when each instruction is processed is stored in condition code flags. The state information is optionally used in the processing of subsequent instructions in the sequence and/or accumulated with previously set state information.
