Arithmetic Pipelines
The technique of pipelining can be applied to various complex and low arithmetic operations to speed up processing time. Pipelines used for arithmetic calculations are called Arithmetic pipelines. In this segment we discuss arithmetic-pipelines based on arithmetic operations. Arithmetic-pipelines are created for simple fixed point and complex floating-point arithmetic operations. These arithmetic operations are well-matched to pipelining because these operations can be efficiently divided in subtasks for the pipeline phases. For applying the arithmetic pipelines we normally use following two types of adder:
I. Carry propagation adder (CPA): It adds two numerals such that carries generated in successive digits are propagated.
II. Carry save adder (CSA): It adds two numerals such that carries generated are not propagated rather these are saved in a carry vector.
