摘要： Power management for a processing system that has multiple processing units, (e.g., multiple graphics processing units (GPUs), is described herein. The processing system includes a power manager that obtains performance, power, operational or environmental data from a power management unit associated with each processor (e.g., GPU). The power manager determines, for example, an average value with respect to at least one of the performance, power, operational or environmental data. If the average value is below a predetermined threshold for a predetermined amount of time, then the power manager notifies a configuration manager to alter the number of active processors (e.g., GPUs), if possible. The power may then be distributed among the remaining GPUs or other processors, if beneficial for the operating and environmental conditions.

摘要： When an instruction is executed on an integrated circuit (IC), an activity level and temperature are measured. A relationship between the activity level and temperature is determined, to estimate the temperature from the activity level. The activity level is monitored and is input to a scheduler, which estimates the IC temperature based on the activity level. The scheduler distributes work taking into account the temperature of various IC regions and may include distributing work to the IC region that has a lowest estimated temperature or relatively lower estimated temperature (e.g., lower than the average IC or IC region temperature). When the utilization level of one or more IC regions is high, the scheduler is configured to reduce the clock speed or the voltage of the one or more IC regions, or flag the regions as being unavailable for additional workload.

摘要： A system and method for reducing power consumption of a video subsystem. A computer system includes multiple display devices supported by a graphics processor. A memory for storing video data for the multiple display devices utilizes multiple channels for higher bandwidth. A systems controller within the graphics processor determines a retraining condition, such as an idle power state, is satisfied for one or more channels of the multiple memory channels. The graphics processor divides each respective screen for the multiple display devices into multiple horizontal bars. For each one of the multiple horizontal bars, the corresponding data may be rearranged from being distributed across the multiple channels to being stored in a single one of the multiple channels. The systems controller determines a given channel is an upcoming free channel. This free channel is retrained while it is free. Retraining may include at least reducing its memory clock (MCLK) frequency.

摘要： Provided is a method for improving performance of a processor. The method includes computing utilization values of components within the processor and determining a maximum utilization value based upon the computed utilization values. The method also includes comparing (i) the maximum utilization value with a first threshold and (ii) differences between the computed utilization values and a second threshold.
