Abstract
A computer for performing immediate calculations by executing an immediate calculation instruction containing a first immediate value and an immediate prefixed instruction containing a second immediate value consists of a register for storing the second immediate value, a prefix state flag for setting a flag in cases where the second immediate value is stored in the register, concatenating unit for concatenating the first immediate value with the second immediate value in cases where the flag in the prefix state flag is set and generating the concatenated immediate value as a first constant, bit extension unit for extending the number of bits in the first immediate value without changing the first immediate value and generating the extended immediate value as a second constant, selector for selecting the first constant generated in the concatenating unit in cases where the flag in the prefix state flag is set and selecting the second constant generated in the bit extension unit in cases where the flag in the prefix state flag is not set, and calculation unit for performing the immediate calculation to process the constant selected in the selector.
