CAP: A General Purpose Computation-in-memory with Content Addressable Processing Paradigm

Demands for efficient computing under memory wall have led to computation-in-memory (CIM) accelerators that leverage memory structure to perform in-situ computing. The content addressable memory (CAM) processing is a CIM paradigm that accomplishes general purpose functions, via sequences of search and update operations on CAM. However, the conventional CAM-based CIM is customized for vector-vector operation only and requires long search-update iterations for computing.
