Abstract
A register content inheriting system contributes for realization of register content inheriting with a hardware of simple construction in a multithread multi-processor. Respective thread execution units and physical common register are provided. Using a register mapping table, a register number to be made reference to from each program is placed in the physical common register. Only as required in inheriting of register content, a relationship of the register mapping table is updated. Upon inheriting the content of the register, the content of the register mapping table is copied.
