The Thread Data Base 1 holds a thread identifier to uniquely identify a thread in the system. The Check means 3 lets, when no thread being a target exist in the same processor, a trap (TRAP) 10 occur. The Issue means 2, when a thread being a target exists in the same processor, at a time of issuing a subsequent instruction, successively inputs a thread 9 to be executed next, as a thread serving as a target, into a pipeline. The Gate (G) means 11 uses data on the execution of a thread as an input for computation of a thread serving as a succeeding target. The Switch means 13 transfers data in a context of a thread to a context of a target thread without inputting the target thread as a non-executable thread into a pipeline while the thread is being executed. |
