Feature tracking

A method comprising:

• storing, using a direct memory access (DMA) system, first data in one or more memories for access by a processor, the first data representative of one or more descriptors associated with a tracked feature that is represented by sensor data;
• reading, using the DMA system, second data stored in the one or more memories by the processor, the second data representative of one or more first locations associated with the tracked feature as determined by the processor using at least a portion of the first data;
• updating, using the DMA system and based at least on the one or more first locations, the first data representative of the one or more descriptors associated with the tracked feature;
• and
• reading, using the DMA system, third data stored in the one or more memories by the processor, the third data representative of one or more second locations associated with the tracked feature as determined by the processor using at least a portion of the first data as updated.

A system comprising:

• a direct memory access (DMA) system to:
• retrieve first data stored in one or more memories by a processor, the first data representative of one or more first locations associated with a tracked feature determined using sensor data;
• determine, based at least on the one or more first locations, one or more descriptors associated with the tracked feature;
• store second data in the one or more memories for the processor, the second data representative of the one or more descriptors associated with the tracked feature;
• and
• retrieve third data stored in the one or more memories by the processor, the third data representative of one or more second locations associated with the tracked feature as determined by the processor using at least a portion of the one or more descriptors.
