ADAPTIVE WAKE-UP FOR POWER CONSERVATION IN A PROCESSOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 17664999 titled 'ADAPTIVE WAKE-UP FOR POWER CONSERVATION IN A PROCESSOR

Simplified Explanation

A processor with multiple processing pipelines and dedicated logic and memory circuits can efficiently manage power consumption based on the current operating mode.

The processor includes different processing pipelines with dedicated logic and memory circuits.
A power management circuit determines when to supply power to each pipeline based on the current operating mode.
When a memory circuit enters a lower power state, data is saved to a different memory circuit that remains powered.
When the memory circuit is powered up again, the data is restored from the different memory circuit.

Original Abstract Submitted

A processor can include various processing pipelines that perform different data processing operations, with different pipelines having dedicated logic and memory circuits. A power management circuit can determine when to supply power to various pipelines, including the logic and memory circuits of the various pipelines, depending on a current operating mode of the processor. When a memory circuit transitions to a lower power state such as a sleep state, data can be saved to a different memory circuit that is not transitioning to a lower power state, and when the memory circuit is powered up again, the data can be restored from the different memory circuit.
