Abstract

A circuit includes a data input that is configured to receive a data word, the data word including at least one operand which is rotated by a number of bits given by a rotation parameter, a first control input that is configured to receive the rotation parameter, a second control input that is configured to receive an indication of an operation to be performed, a first subcircuit that is configured to generate an operation- and rotation-dependent bit mask from the rotation parameter and the indication of the operation to be performed, a second subcircuit which is configured to process the at least one operand as a function of the bit mask and the operation to be performed, wherein the operand and the operation result generated by the processing remain in the rotated state, and a data output which is configured to output the operation result.
