What is it about?

An innovative design of high throughput of FIR filter through the effective use of retiming and efficient add-multiply operation is presented in this article. Efficient linear and square root carry select adder structures are obtained by combining modified forms of carry look ahead and carry skip adder concepts to concatenated CSLA modules. Cadence software with 45nm standard cell library is used for the design and implementation
