Abstract
An event-based vision sensor system comprises an event-based pixel array including pixels that detect light, a readout circuit for reading out events associated with light received by each pixel and with the position it occupies in the array, and a memory controller that enables writing of each event, or event-related data, associated with a certain pixel to a certain address in a memory.
Claims19
An event-based vision sensor system, comprising:
- an event-based pixel array comprising pixels that detect light;
- a readout circuit for reading out events associated with light received by each pixel and with the position it occupies in the array;
- and
- a memory controller that enables writing of each event, or event-related data, associated with a certain pixel to a certain address in a memory;
- wherein the memory controller implements a mapping between pixels of the event-based pixel array and addresses in the memory.

A method of operation of an event-based vision sensor system, comprising:
- detecting light with an event-based pixel array;
- reading out events associated with light received by each pixel and with the position it occupies in the array with a readout circuit;
- and
- a memory controller writing of each event, or event-related data, associated with each pixel to different mapped address in a memory.

An event-based vision sensor system, comprising:
- an event-based pixel array comprising pixels that detect light;
- a readout circuit for reading out events associated with light received by each pixel and with the position it occupies in the array;
- and
- a memory controller that enables writing of each event, or event-related data, associated with a certain pixel to a certain address in a memory, wherein the memory controller assigns each pixel a dedicated address of the memory.
