Abstract
An apparatus and method are provided for executing a push all/pop all instruction in a pipeline microprocessor. The apparatus includes an instruction buffer and a translator. The instruction buffer provides the push all/pop all instruction, directing the microprocessor to store/retrieve multiple operands to/from a stack. The translator generates a sequence of micro instructions to store/retrieve the multiple operands. Accesses to a pair of operands which are together aligned are combined into a single access.
