Abstract
PURPOSE:To shorten a program execution time, by storing only the address data of the argument of a sub routine not including the identifier of an operand in a stack. CONSTITUTION:A parameter stack 7 and a ZK stack 8 are provided on a data memory 4. When the argument of the sub routine appears in evaluation by an instruction interpretation part 1, an arithmetic processing part 2 stores only the address value of the argument in the parameter stack 7 when the argument is the operand, and also, when the argument is a constant operand, the direct numeral is stored once in the ZK stack 8, and also, the address value of a storing destination is stored in the parameter stack 7. As a result, in the parameter stack 7, only the address data is always stored, and no identifier of the operand is included. In such a way, it is not required to urge the re-evaluation of the argument from the arithmetic processing part 2 to the instruction interpretation part 1 at the time of executing the sub routine, then,the execution speed of program can be accelerated.
