Performance/Cost Evaluation of Pipelined Cordic Function Units.

摘要

To measure the desirability of a function unit, the performance/cost ratio is used. The performance/cost ratio is the number of functions that can be initiated per second divided by the cost of the function unit. The cost is considered to be only the cost of the integrated circuits needed to implement a design. It does not include the cost of the interface, power supplies, circuit boards or wiring. A simple model can be constructed, however, to include these costs. Several types of structures are used to implement the cordic algorithm.
