Abstract
A device and a method for performing bitwise manipulation is provided. Multiple bitwise logic circuits are coupled to an instruction decoder, a register array and a rotator. Each bitwise logic circuit includes input multiplexers connected to an output multiplexer. The instruction decoder receives a bit manipulation instruction and sends to each corresponding input multiplexer a control signal based on a type of the instruction. Each input multiplexer of each bitwise logic circuit receives a control signal, a constant signal that has a value that is indifferent to the value of the mask, and a mask affected signal that has a value that is responsive to a value of an associated mask bit. Each input multiplexer selects between the constant signal and the mask affected signal based on the control signal, and outputs a selected signal. Each output multiplexer receives selected signals from each of the corresponding input multiplexers, and elects between the selected signal based on a value of an associated manipulated register bit and based on a value an associated control register bit.
