摘要：CSA (Carry Save Adder) is a type of digital adder used in computer architecture to the computer sum ofthree or more n-bit number in binary. It differ from other digital adders in that is outputs two numbers of the samedimensions as the inputs one which is a sequence of partial sum bits and another which is a sequence of carry bits. CSAis used to implement the adder circuit. In this paper, Look up Table and Booth Encoder techniques are used. LUT is forspeed of calculation, which is an array that replaces runtime computation with a simpler array indexing operation. Thesavings in terms of processing time can be significant, since retrieving a value from memory is after faster thanundergoing an “Expensive” computation operation. Booth Encoder is used to or input, output reduces the number ofpartial products. These techniques are used to reduce the power, time delay and area by using of modelsim software.We can attain 30% speed improvement and 22% power reduction in Design units of DSP/multimedia Applications.
