ABSTRACT:
An instruction having two operands includes a field specifying the bit length of a source operand and a field specifying the bit length of data to be operated upon by the execution unit. Based on size information stored in these fields, the operand bit length is modified, which avoids need for modification of the bit length of an operand by use of a macro instruction at the time of execution of an operation based on the two operands. Consequently, the program execution speed can be improved.
