Systems and methods to flush data in persistent memory region to non-volatile memory using auxiliary processor

A system on a chip (SoC) implemented on an integrated circuit that enables data stored in a persistent memory region to be preserved when a processor fails, comprising:

• a main processor on the integrated circuit that is communicatively coupled to volatile memory and non-volatile memory in a computing system, the volatile memory comprising the persistent memory region;
• an auxiliary processor on the integrated circuit that is communicatively coupled to the volatile memory and the non-volatile memory;
• and
• instructions that are executable by the auxiliary processor to cause data in the persistent memory region of the volatile memory to be transferred to the non-volatile memory in response to a failure of the main processor.

A method for enabling data stored in a persistent memory region in volatile memory to be preserved when a main processor on a computing system fails, the method being performed by an auxiliary processor that is located on a same system on a chip (SoC) as the main processor, the SoC being implemented on an integrated circuit, the method comprising:

• receiving control of the computing system from the main processor on the integrated circuit in response to an error that makes the main processor inoperable;
• causing the data in the persistent memory region in the volatile memory to be transferred to non-volatile memory;
• and
• causing the computing system to be rebooted after the data has been transferred to the non-volatile memory.
