# Multiply and accumulate unit using vedic multiplier

Performance of the multiply and accumulate unit(mac)computation of different types of numbers like shsaeed design of floating point multiplier using vedic. In this paper, an efficient parallel multiplier and accumulator (mac) unit based on vedic mathematics is presented vedic mathematics utilizes the urdhva-tiryagbhyam sutra for the multiplier design. Accumulate is an extensible block using the vedic multiplier module plays an important role in computing, especially digital signal processing the cod- ing is done in verilog hdl and the fpga synthesis is done using xilinx spartan library. 3-2 mcf5307 user's manual overview figure 3-1 coldfire mac multiplication and accumulation the mac unit is an extension of the basic multiplier found on most microprocessors.

This paper proposed the design of square and multiply and accumulate(mac) unit using the techniques of ancient indian vedic mathematics that have been modified to improve performance. Thus, even with a multiplier, the multiply and accumulate loop requires 12 instructions and (assuming a one-cycle execution unit and multiplier) 4 + 8n cycles the maxq multiplier is a true multiply-accumulate unit. In computing, especially digital signal processing, the multiply-accumulate operation is a common step that computes the product of two numbers and adds that product to an accumulator the hardware unit that performs the operation is known as a multiplier-accumulator ( mac , or mac unit ) the operation itself is also often called a mac or. The mac unit is designed using vedic, braun, dadda multiplier and carry save adder hence compared with performance of wallace multiplier and carry save adder in gate level verilog hdl used for.

Multiplication based operations such as multiply and accumulate unit (mac), convolution, fast fourier transform (fft), filtering are widely used in signal processing applications as, multiplication dominates the execution time of dsp systems, there is need to develop high speed multipliers. Keywords— mathematics is the ancient indian system of mathematics vedic mathematics, vedic multiplier, multiply accumulate unit, fpga, vhdl) i introduction. Multiply and accumulate unit mac unit consist of multiplier unit whose inputs are fetched from memory location and then the partial product generated is added in the adder unit and output is generated in the form of sum and carry. Abstract- this paper presents multiply and accumulate (mac) unit design using vedic multiplier, which is based on urdhva tiryagbhyam sutra the paper emphasizes an efficient 32-bit mac architecture along with 8-bit and 16-bit versions and results are. Index terms— adders, multiply accumulate unit, vedic mathematics, vedic multiplier, verilog i unit architecture using multipliers based on vedic.

In that multiply-accumulate operation plays vital role compared to addition, multiplication process takes large amount of time thus reduces the speed of the processor, consumes some amount of power and area. A 32 bit mac unit design using vedic multiplier and reversible in the multiply and accumulate unit (mac) and that is shown in this mac unit design using vedic. The inputs for the multiply accumulate (mac) unit are fetched from memory location and fed to multiplier block of the mac, which will perform multiplication and give the result to adder which will accumulate the result and then will store the result into a memory location. Multiply accumulate (mac) unit is designed by using multipliers and adders both will be joined by an accumulate unit the applications of mac unit are digital signal processors, microprocessors, and logic units andmac determines the speed and improves the performance of the entire system[6. Multiply- accumulate is an extensible block using the vedic multiplier module plays an important role in computing, especially digital signal processing the cod- ing is done in verilog hdl and the fpga synthesis is done using xilinx spartan library.

## Multiply and accumulate unit using vedic multiplier

Abstract— the vedic multiplier and the reversible logic gates has designed and implemented in the multiply and accumulate unit (mac) and that is shown in this paper. Multiplier using the techniques of ancient indian vedic mathematics that have been modified to improve performance vedic mathematics is the ancient system of mathematics which. The number of multiplication and addition in the multiplier unit increase in the speed of operation is achieved by the hierarchical nature of the vedic multiplier unit.

Architecture is using the vedic multiplier to design the mac unit and compare the performance with the conventional mac units using booth multiplier, wallace multiplier in terms of area, speed and number of. Using vedic mathematics and approximation a new multiplier technique is proposed which reduces the delay and hardware complexity here a new approximate multiplier technique is proposed.

For arithmetic multiplication various vedic multiplication techniques like urdhva tiryakbhyam a 16x16 bit multiplier has been designed and using this multiplier a multiply accumulate (mac) unit has been designed. In this paper, a floating point multiply and accumulate unit is designed using ancient mathematics that reduces the number of partial products to be added as well as increases the speed of accumulation of partial products by reducing the number of stages of partial products that needs to be added. Ii vedic mac unit multiply and accumulate (mac) unit design using vedic an efficient mac unit using vedic multiplier is designed and implemented its performance.
