Abstract
A pipeline computer having functions of scoreboard control includes a dependency detection unit provided in the scoreboard for detecting dependency of data between a preceding instruction and a following instruction, the preceding instruction being an instruction which executes prior to the following instruction; and an ensuring unit for the dependency of data detected by the detection unit based on an interlock operation at pipeline processes when an interruption occurs. An interruption instruction waits for completion of an instruction which already starts to execute prior to the interruption instruction, and all register bits on the scoreboard indicating the in use state are reset to the not used state to ensure the dependency of data.
