What Is the Difference Between Scalar and Superscalar Processors?
There are different types of central processing units (CPUs) available for computers. These types of CPUs do not really differ in terms of processing hardware and architecture. Most of them perform the basic tasks of a CPU such as reading and writing data, basic arithmetic, and address jumping. They can, however, differ in terms of bus sizes and processor architecture. Several types of computer processor hardware are available, two of which are the scalar and superscalar processors. A processor that executes scalar data is called a scalar processor. Using fixed point operands, integer instructions are executed by scalar processors even in their simplest state. More powerful scalar processors usually execute both floating point and integer operations. Recently produced scalar processors contain both a floating point unit and an integer unit, all on the same CPU chip. Most of these modern scalar processors use instructions of the 32-bit kind.
