Abstract: Systems, apparatuses, and methods for managing power and performance in a computing system. A system management unit detects a condition indicating a change in a power-performance state of a given computing unit is indicated. In response to detecting the indication, the system management unit is configured to initiate a change to a frequency of a clock signal generated by an adaptive oscillator by changing a voltage supplied to the adaptive oscillator. The adaptive oscillator is configured to rapidly change a frequency of the clock signal generated in response to detecting a change in a droopy supply voltage of the adaptive oscillator. The new frequency generated by the adaptive oscillator is based in part on a difference between the droopy supply voltage and a regulated supply voltage of the adaptive oscillator.

Abstract: A GPU filters graphics workloads to identify candidates for profiling. In response to receiving a graphics workload for the first time, the GPU determines if the graphics workload would require the GPU shaders to use fewer resources than would be spent profiling and determining a resource allocation for subsequent receipts of the same or a similar graphics workload. The GPU can further determine if the shaders are processing more than one graphics workload at the same time, such that the performance characteristics of each individual graphics workload cannot be effectively isolated. The GPU then profiles and stores resource allocations for a plurality of shaders for processing the filtered graphics workloads, and applies those stored resource allocations when the same or a similar graphics workload is received subsequently by the GPU.

Abstract: A GPU of a processor performers load balancing by enabling and disabling CUs based on the GPU's processing load. A power control module identifies a current processing load of the GPU based on, for example, an activity level of one or more modules of the GPU. The power control module also identifies an expected future processing load of the GPU based on, for example, a number of threads (wavefronts) scheduled to be executed at the GPU. Based on a combination of the current processing load and the expected future processing load, the power control module sets the number of CUs of the GPU that are enabled and the number that are disabled (e.g. clock gated or power gated). By changing the number of enabled CUs based on processing load, the power control module maintains performance at the GPU while conserving power.

Abstract: Interactive electronic book operating systems and methods for displaying and allowing customization of content of scientific, engineering and other technical and professional digital books. The systems and methods allow for a single screen for displaying digital books covering scientific and technical topics having a classical look and feel on operating platforms(such as portable laptops, desktops, and small handheld displays) that are capable of running the Java Virtual Machine. The display screen can include icon toolbars about the screen and/or directly on the screen to manipulate the pages and content of the digital book.
