Asynchronous readout encoding for event-based vision sensor

An encoding format for transmitting event data from an event-based vision sensor, the encoding format comprising:

• a row address most significant bit (MSB) package including a first prefix code and content bits for encoding MSB row address information;
• a row address least significant bit (LSB) package including a second prefix code and content bits for encoding LSB row address information, wherein the second prefix code is different from the first prefix code;
• a column address MSB package including a third prefix code and content bits for encoding MSB column address information, wherein the third prefix code is different from the first and second prefix codes;
• and
• a column address LSB package including a fourth prefix code and content bits for encoding LSB column address information, wherein the fourth prefix code is different from the first, second, and third prefix codes,
• wherein at least one of the first, second, third, and fourth prefix codes has a different length from at least one other one of the first, second, third, and fourth prefix codes.
