Find the fundamental functions of an arithmetic/logic unit (ALU) of a fixed-point processor in the following list, SmallCircle Addition/subtraction SmallCircle Multiplication/Division SmallCircle Square and squareroot computation SmallCircle Logic operations SmallCircle Bit shifting and rotation SmallCircle Data moving and memory accessing SmallCircle Program flow control

Solution

The basic functions of ALU are addition and subtraction, Logic operations, Bit shifting operations. The ALU performs subtraction using two\'s complement. It perfoms bitwise logical operations such as AND, OR and EX-OR functions. The bit shifting operations performed by ALU are Arithmetic shift, logical shift, rotate and rotate through carry. there are the fundamental operations. But an ALU can perform complex operations like calculating the square root by employing additional circuitry.
