shifter device, the programmable shifter device having: a first input for receiving data from said memory unit; a second input, which is used receiving the arithmetic output; a third input for receiving a computer to execute its instruction opcodes; and shift output, and its shift to provide ...
In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU). Some processors contain more than one AU -- for example, one for fixed-point operations and another for floating-point operations. In computer systems, floating-point computations are some...

An arithmetic logic unit (30) for a digital signal processor (DSP) contains circuitry for preshifting (46, 48) and prerounding (54) the 2's- complement fractional input operands (32, 34) before they are used by a carry look-ahead adder (56). The preshifting (46, 48) provides for ...
It is cleared by all other arithmetic operations. The CY flag is also affected by Shift and Rotate instructions. Auxiliary Carry flag (AC) This flag is set when the last arithmetic operation that was executed results in a carry into (addition) or borrow from (subtraction) the high-order ...
