PURPOSE:To enable the content of a register to be recovered and to accelerate the call of a function and a predicate, by replacing the content of argument register address information at the time of calling the function and the predicate, and setting the required value of the argument on the register. CONSTITUTION:The value of the argument required for the call of the function and the predicate is stored in one or more registers from the forefront of plural argument register in a file 1, and when it is required to store the argument according to the execution of the function and the predicate, the content of the register holding the said value is preserved as it is, and the value is stored in an other register. When another function or the predicate out of called functions or predicates is required, the content of an argument number register 2 is replaced via selectors 3 so that the register required at that time can be positioned at the forefront of a register group. Therefore, it is possible to execute the call of the next function or the predicate at high speed. |
