摘要： A core switching system includes a mode switching module that receives a switch signal to switch operation between a first mode and a second mode. During the first mode, instructions associated with applications are executed by a first asymmetric core, and a second asymmetric core is inactive. During the second mode, the instructions are executed by the second asymmetric core, and the first asymmetric core is inactive. A core activation module stops processing of the applications by the first asymmetric core after interrupts are disabled. A state transfer module transfers a state of the first asymmetric core to the second asymmetric core. The core activation module allows the second asymmetric core to resume execution of the instructions and the interrupts are enabled.

摘要： The present disclosure describes techniques and apparatuses for switching between processor cache and random-access memory. In some aspects, the techniques and apparatuses are able to reduce die size of application-specific components by forgoing dedicated random-access memory (RAM). Instead of using dedicated RAM, a memory having a cache configuration is reconfigured to a RAM configuration during operations of the application-specific component and then, when the operations are complete, the memory is configured back to the cache configuration. Because many application-specific components already include memory having the cache configuration, reconfiguring this memory rather than including a dedicated RAM reduces die size for the application component.

摘要： Embodiments of a method and system for heterogeneous memory control are disclosed. The embodiments include components of a Memory Manager that receive usage information of a memory subsystem of a host system, the memory subsystem including internal memory and external memory. The Memory Manager also receives client information of one or more clients that are coupled to and/or integrated with the host system. A request or call for internal memory is also received at the Memory Manager from the clients. The Memory manager automatically controls the memory in accordance with one or more of the request, the usage information and the client information. The control includes allocating a portion of the internal memory to the client, remapping one or more areas of internal memory from a first client to a second client, and/or reorganizing the memory by remapping external memory to internal memory. Other embodiments are described and claimed.

摘要： A processing system may include a performance monitoring unit (PMU), a machine accessible medium, and a processor responsive to the PMU and the machine accessible medium. Instructions encoded in the machine accessible medium, when executed by the processor, may determine whether performance details for the processing system should be collected, based at least in part on a predetermined monitoring policy for the processing system. The instructions may generate performance data for the processing system, based at least in part on data obtained from the PMU. The instructions may determine whether the processing system should be reconfigured, based at least in part on the performance data and a power policy profile for the processing system. The instructions may automatically adjust power consumption of the processing system by using the PMU to reconfigure the processing system. Other embodiments are described and claimed.
