Systems and methods for heat map generation and operation

A system comprising:

• a host device;
• and
• a storage device communicatively coupled to the host device via a bus, the storage device being configured to:
• determine a first region in a first heat map of the storage device based on an instruction received by the storage device from the host device;
• generate a prefetch request based on a number of times the first region of the first heat map is accessed by the host device;
• prefetch data or instructions stored at an address of the storage device corresponding with the first region of the first heat map based on the prefetch request and associated with the instruction received by the storage device;
• send the prefetched data or instructions from the first region of the first heat map to the host device;
• update a second heat map of the storage device based on the instruction received from the host device;
• determine based on information received from the host device that a rate of the prefetched data or instructions from the first region of the first heat map that are used by the host device is less than a threshold value;
• and
• switch the second heat map with the first heat map based on determining that the rate of the prefetched data or instructions from the first region of the first heat map is less than the threshold value.

A non-transitory computer readable medium comprising stored instructions, which when executed by a storage device, cause the storage device to:

• determine a first region in a first heat map of the storage device based on an instruction received by the storage device from a host device connected to the storage device;
• generate a prefetch request based on a number of times the first region of the first heat map is accessed by the host device;
• prefetch data or instructions stored at an address of the storage device corresponding with the first region of the first heat map based on the prefetch request and associated with the instruction received by the storage device;
• send the prefetched data or instructions from the first region of the first heat map to the host device;
• update a second heat map of the storage device based on the instruction received from the host device;
• determine based on information received from the host device that a rate of the prefetched data or instructions from the first region of the first heat map that are used by the host device is less than a threshold value;
• and
• switch the second heat map with the first heat map based on determining that the rate of the prefetched data or instructions from the first region of the first heat map is less than the threshold value.
