摘要： Briefly, a method and apparatus adjusts the power consumption level of an integrated circuit by dynamically scaling the clock frequency based on the real-time determined power consumption level. In one example, the method and apparatus changes an actual clock frequency of the integrated circuit to an effective clock frequency based on the maximum clock frequency and the difference between the threshold power consumption level and the actual power consumption level of the integrated circuit in the previous sampling interval. In one example, an effective clock frequency of the integrated circuit in the current sampling interval is determined. In one example, the difference between the maximum and effective clock frequencies in the current sampling interval is proportional to the difference between the threshold and actual power consumption levels in the previous sampling interval. The actual clock frequency of the integrated circuit is changed to the determined effective clock frequency.

摘要： A method of performing an input/output process containing a programmed input/output (PIO) instruction in a multiprocessor system including at least two processors each having an associated I/O bus with I/O devices connected thereto. The method has the steps of storing a unique address and a bus location for each I/O device in a device location table, determining the address of a referenced I/O device prior to performing the PIO instruction, reading the corresponding I/O bus location of the referenced I/O device from the device location table and executing the input/output process on the prescribed processor associated with the I/O bus to which the referenced I/O device is located. The method is used in conjunction with a task scheduler including a process control block for each scheduled process. When the PIO instruction references a device on the local I/O bus, the input/output process is executed normally. To execute the input/output process on a remote processor, a locked descriptor identifying the remote processor is placed in the process control block for that process. The input/output process is then scheduled for execution on the remote processor.

摘要： Methods and apparatuses are provided for power control in a processor. The apparatus comprises a plurality of operational units arranged as a group of operational units. A power consumption monitor determines when cumulative power consumption of the group of operational units exceeds a threshold (e.g., either or both of the cumulative power threshold and the cumulative power rate threshold) during a time interval, after which a filter for issuing instructions to the group of operational units suspends instruction issuance to the group of operational units for the remainder of the time interval. The method comprises monitoring cumulative power consumption by a group of operational units within a processor over a time interval. If the cumulative power consumption of the group of operational units exceeds the threshold, instruction issuance to the group of operational units is suspended for the remainder of the time interval.
