  • Patent number: 8447959
    Abstract: A plurality of register windows in a multithread processor are each provided for a corresponding thread and capable of storing data to be used for instruction processing in an arithmetic unit. A work register in the multithread processor is capable of mutually transferring data with respect to the register windows and the arithmetic unit. A multithread control unit in the multithread processor controls data transfer among the register windows, the work register and the arithmetic unit on the basis of an execution thread identifier identifying the thread to be executed in the arithmetic unit. This enables conducting the multithread processing at a high speed.

  • Patent number: 8438366
    Abstract: Multiple data processing instructions instruct a computing device to process multiple data including first data and second data. When a multiple data processing instruction is decoded, two allocatable registers are selected. One is used to store the result of a processing operation performed on first data by one processing unit, and the other is used to store the result of a processing operation performed on second data by another processing unit. Those stored processing results are then transferred to result registers. Normal data processing instructions, on the other hand, instruct a processing operation on third data. When a normal data processing instruction is decoded, one allocatable register is selected and used to store the result of processing that a processing unit performs on the third data. The stored processing result is then transferred to a result register.
