A field‐programmable gate array‐based reconfigurable parallel computing unit to calculate the Walsh–Hadamard transform is proposed. The architecture can process long‐duration signals with a large number of samples. Obtained results demonstrate its versatility and usefulness in applications requiring online digital signal processing, utilising few resources in low‐cost devises as Cyclone II 2C20 and Cyclone IV EP4CE22.
