This paper presents a novel energy-efficient and Dynamically Reconfigurable Computing Circuit (DRC²) concept based on memory architecture for data-intensive (imaging, ...) and secure (cryptography, ...) applications. The proposed computing circuit is based on a 10-Transistor (10T) 3-Port SRAM bitcell array driven by a peripheral circuitry enabling all basic operations that can be traditionally performed by an ALU. As a result, logic and arithmetic operations can be entirely executed within the

Moreover, the proposed computing circuit can perform extremely-parallel operations enabling the processing of large volume of data. A test case based on image processing application and using the saturating increment function is analytically modeled to compare conventional and DRC²-based approaches. It is demonstrated that DRC²-based approach provides a reduction of clock cycle number of up to 2x. Finally, potential applications and must-be-considered changes at different design levels are discussed.
