Always-On Processor as a Coprocessor |
| 摘要 |
A system on a chip (SOC) may include a component that remains powered when the remainder of the SOC is powered off. The component may be configured to power up other components of the SOC while keeping the central processing unit (CPU) processors powered down, in order to perform a task assigned to such other component(s). The always-on component may further include a processor, in some embodiments, which may interact with the other components to perform the task. In an embodiment, the processor within the always-on component may execute operating system (OS) software to interact with the other components while the CPU processors are powered down. |

1. A system on a chip (SOC) comprising:
at least one first processor forming a central processing unit (CPU); a peripheral component; and a first component coupled to the CPU and the peripheral component, wherein the first component is configured to remain powered on during times that the CPU and the peripheral component are powered off, and wherein the first component is configured to wake the peripheral component and interact with the peripheral component to perform at least one task assigned to the peripheral component by the CPU without waking the CPU. |
