Abstract

Se ejecuta una instrucción para llevar a cabo una operación de desplazamiento y división. La ejecución incluye desplazar un valor en una dirección especificada una cantidad seleccionada para proporcionar un dividendo, la cantidad seleccionada siendo definida por el usuario. El dividendo se divide por un divisor para obtener un cociente. Al menos un subconjunto del cociente se selecciona como resultado. El resultado será utilizado en el procesamiento dentro del entorno de computación.
