Abstract

Se ejecuta una instrucción aritmética/lógica que tiene operandos de memoria enclavados, cuando se ejecuta obtiene un segundo operando de una ubicación de memoria y guarda una copia temporal del segundo operando, la ejecución realiza una operación aritmética o lógica con base en el segundo operando y un tercer operando y almacenar el resultado en la ubicación de memoria del segundo operando, y subsecuentemente almacena la copia temporal en un primer registro.
