REDUCING LATENCY OF CHANGING AN OPERATING STATE OF A PROCESSOR FROM A LOW-POWER STATE TO A NORMAL-POWER STATE - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17727685 Titled 'REDUCING LATENCY OF CHANGING AN OPERATING STATE OF A PROCESSOR FROM A LOW-POWER STATE TO A NORMAL-POWER STATE'
Simplified Explanation
This abstract describes techniques for reducing the time it takes for a processor to switch from a low-power state to a normal-power state. One method involves the hardware system notifying the processor that a transaction layer packet will be sent to it in the future, prompting the processor to switch to the normal-power state. Another method involves the processor receiving a transaction layer packet from the hardware system, which also triggers the switch to the normal-power state. These techniques aim to minimize latency in transitioning the processor's operating state.
Original Abstract Submitted
Techniques are described herein that are capable of reducing latency of changing an operating state of a processor from a low-power state to a normal-power state. For example, providing a notification from a hardware system to the processor or receiving the notification at the processor, indicating that a transaction layer packet will be provided to the processor at a future time, may trigger the processor to change the operating state from the low-power state to the normal-power state. In another example, receipt of a transaction layer packet at the processor from a hardware system may trigger the processor to change the operating state from the low-power state to the normal-power state.
