摘要:
In an embodiment, a processor includes a core domain with a plurality of cores and a power controller having a first logic to receive a first request to increase an operating voltage of a first core of the core domain to a second voltage, to instruct a voltage regulator to increase the operating voltage to an interim voltage, and to thereafter instruct the voltage regulator to increase the operating voltage to the second voltage. Other embodiments are described and claimed.

I/O logic can be separated into critical and non-critical portions, with the non-critical portions being powered down during processor idle. The I/O logic is separated into gate logic and ungated logic, where the ungated logic continues to be powered during a processor deep sleep state, and the gated logic is powered off during the deep sleep state. A power control unit can trigger the shutting down of the I/O logic.

Embodiments of systems, apparatuses, and methods for energy efficiency and energy conservation including enabling autonomous hardware-based deep power down of devices are described. In one embodiment, a system includes a device, a static memory, and a power control unit coupled with the device and the static memory. The system further includes a deep power down logic of the power control unit to monitor a status of the device, and to transfer the device to a deep power down state when the device is idle. In the system, the device consumes less power when in the deep power down state than in the idle state.

In one embodiment, the present invention includes a processor having multiple domains including at least a core domain and a non-core domain that is transparent to an operating system (OS). The non-core domain can be controlled by a driver. In turn, the processor further includes a memory interconnect to interconnect the core domain and the non-core domain to a memory coupled to the processor. Still further, a power controller, which may be within the processor, can control a frequency of the memory interconnect based on memory boundedness of a workload being executed on the non-core domain. Other embodiments are described and claimed.
摘要:
Remapping technologies for execution context swap between heterogeneous functional hardware units are described. A computing system includes multiple registers configured to store remote contexts of functional units. A mapping table maps the remote context to the functional units. An execution unit is configured to execute a remapping tool that intercepts an operation to access a remote context of a first functional unit of the plurality of functional units that is taken offline. The remapping tool determines that the first functional unit is remapped to a second functional unit using the mapping table. The operation is performed to access the remote context that is remapped to the second functional unit. The first functional unit and the second functional unit may be heterogeneous functional units.

摘要:
Processor context save latency is reduced by only restoring context registers with saved state that differs from the reset value of registers. A system agent monitors access to the design blocks and sets a dirty bit to indicate which design block has registers that have changed since the last context save. During a context save operation, the system agent bypasses design blocks that have not had context changes since the latest context save operation. During a context restore operation the system agent does not restore the context registers with saved context values that are equal to the reset value of the context register.
