Abstract: In regard to a scheduling method in a multithreading processor, a thread to be executed is dynamically selected from the threads allotted to the context units according to an operation state of the multithreading processor, and the number of threads to be executed simultaneously or the combination thereof is changed. Also, at the time of context switching, threads to be allotted to the context units are dynamically selected according to an operation state of the multithreading processor. As an example of a method for deciding the operation state, the decision is made by whether a set reference value is exceeded by the number of fetch stall times in a predetermined period on a thread-by-thread basis, number of missing cache times, memory access latency, IPC counter, or the like.

Abstract: A following CC read instruction which is decoded simultaneously with a previous CC update instruction is developed into a multiflow. The first flow is set to a no-operation. A CC renaming update is executed by a CC renaming map update processing unit by the decoding of the previous CC update instruction. The resultant instruction is stored into a CC read instruction multiflow instruction word register. At the next second flow, the CC read instruction is issued from the multiflow instruction word register and, in a state where another instruction is not simultaneously issued, a CC renaming map is referred to by a CC renaming map reference processing unit by the decoding of the CC read instruction.

Abstract: A reliable optical transmission system with an improved signal control mechanism that avoids abrupt power variations of light beams, thereby preventing optical supervisory channel (OSC) signals from experiencing errors. An optical amplifier amplifies main signals under the control of an optical amplifier controller, which spends a first predetermined time to raise the output power of the optical amplifier up to a desired level. A pump light source produces a pump beam for injection to a fiber-optic transmission line so as to make it serve as an amplifying medium. The pump light source is controlled by a pump light source controller that spends a second predetermined time to raise the pump beam to a desired power level. This stepwise start-up process of the amplifier power and pump beam power prevents OSC signals from experiencing abrupt power variations.
