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.
