A high-speed and low-voltage associative co-processor with exact Hamming

A high-speed and low-voltage associative co-processor with exact Hamming

A high-speed and low-voltage associative co-processor with exact Hamming or Manhattan distance estimation is presented. The word-parallel and hierarchical search architecture is achieved using a logic-in-memory digital implementation. In the bit-serial search architecture, it is important to shorten...
