In Windows XP and 2000: Operating Systems "Minimal Power Management" profile must be active in "Power Schemes". A PPM driver was also released by AMD that facilitates this. [5] In Windows Vista and 7: "Minimum processor state" found in "Processor Power Management" of "Advanced Power Settings" should be lower than "100%".
CodeAnalyst by AMD: Linux, Windows C, C++, Objective C .NET, Java (works at the executable level) AMD uProf supersedes CodeAnalyst and CodeXL for CPU and Power profiling on AMD processors. GUI based code profiler; does only basic timer-based profiling on Intel processors. Based on OProfile. Free/open source (GPL) or proprietary AMD CodeXL by AMD
ACPI 1.0 (1996) defines a way for a CPU to go to idle "C states", but defines no frequency-scaling system. ACPI 2.0 (2000) introduces a system of P states (power-performance states) that a processor can use to communicate its possible frequency–power settings to the OS. The operating system then sets the speed as needed by switching between ...
The power management for microprocessors can be done over the whole processor, or in specific components, such as cache memory and main memory. With dynamic voltage scaling and dynamic frequency scaling, the CPU core voltage, clock rate, or both, can be altered to decrease power consumption at the price of potentially lower performance. This is ...
The Linux kernel has a subsystem called "cpufreq", tunable by power-scheme and command line, devoted to the control of the operating frequency and voltage of a CPU. Linux runs on Intel, AMD, and other makes of CPU. [13] [14] Newer version Windows 10 and Linux kernel support Intel Speed Shift Technology. In contrast, AMD has supplied and ...
CodeXL's GPU profiler collects and visualizes hardware performance counters data, application trace, kernel occupancy, and offers hotspot analysis for AMD GPUs and APUs. . The profiler gathers data from the OpenCL runtime, and from the GPU/APU itself during the execution of the kernels, and can be used to discover performance bottlenecks and optimize kernel execut

AMD CodeAnalyst is a GUI-based code profiler for x86 and x86-64-based machines.CodeAnalyst has similar look and feel on both Linux and Microsoft Windows platforms. CodeAnalyst uses specific hardware profiling techniques which are designed to work with AMD processors, as well as a timer-based profiling technique which does not require specific hardware support; this allows a subset of profiling ...
