Description: ABSTRACT:
Low power consumption and smaller area are some of the most important criteria for the
fabrication of DSP systems and high performance systems. Optimizing the speed and
area of the multiplier is a major design issue. However, area and speed are usually
conflicting constraints so that improving speed results mostly in larger areas. In our
project we try to determine the best solution to this problem by comparing a few
multipliers.
This project presents an efficient implementation of high speed multiplier using the shift
and add method, Radix_2, Radix_4 modified Booth multiplier algorithm. In this project
we compare the working of the three multiplier by implementing each of them separately
in FIR filter. Platform: |

Description: 比较好的带符号数乘法的方法是布斯(Booth)算法。它采用相加和相减的操作计算补码数据的乘积。Booth算法对乘数从低位开始判断，根据两个数据位的情况决定进行加法、减法还是仅仅移位操作。判断的两个数据位为当前位及其右边的位(初始时需要增加一个辅助位0)，移位操作是向右移动。-Signed multiplication better way to Booth (Booth) algorithm. It uses the sum and subtraction calculations complement the operation of the data product. Booth algorithm multiplier from the lower to the judge, according to the two data bits decide to add, subtract, or just shift operation. The two bits of data to determine the current position and the right bit (the initial need to add an auxiliary position 0), the shift operation is right. Platform: |

Description: Parallel FIR filter is the prime block of many modern communication application such as MIMO, multi-point transceivers
etc. But hardware replication problem of parallel techniques make the system more bulky and costly. Fast FIR algorithm
(FFA) gives the best alternative to traditional parallel techniques. In this paper, FFA based FIR structures with different
topologies of multiplier and adder are implemented. To optimize design different multiplication technique like add and
shift method, Vedic multiplier and booth multiplier are used for computation. Various adders such as carry select adder,
carry save adder and Han-Carlson adder are analyzed for improved performance of the FFA structure. The basic objective
is to investigate the performance of these designs for the tradeoffs between area, delay and power dissipation. Comparative
study is carried out among conventional and different proposed designs. The advantage of presented work is that; based on
the constraints, one can select the suitable design for specific application. It also fulfils the literature gap of critical analysis
of FPGA implementation of FFA architecture using different multiplier and adder topologies. Xilinx Vivado HLS tool is
used to implement the proposed designs in VHDL. Platform: |
