SINGLE PRECISION FLOATING POINT MULTIPLIER USING SHIFT AND ADD ALGORITHMAM Publications
Floating-point numbers are widely adopted in many applications due to their dynamic representation
capabilities. Basically floating point numbers are one possible way of representing real numbers in binary format.
Floating-point representation is able to retain its resolution and accuracy compared to fixed-point representations.
Multiplying floating point numbers is also a critical requirement for DSP applications involving large dynamic range.
The IEEE has produced a standard to define floating point representation and arithmetic which is known as IEEE
754 standards and which is the most common representation today for real numbers on computer. The IEEE 754
standard presents two different floating point formats, Binary interchange format and Decimal interchange format.
This paper presents a single precision floating point multiplier based on shift and add algorithm that supports the
IEEE 754 binary interchange format..
Floating point ALU using VHDL implemented on FPGAAzhar Syed
Description: An arithmetic unit based on IEEE754 single precision standard for floating point numbers has been targeted to implement on Spartan-6 XC6SLX45 FPGA Board. The hardware description language used to program the FPGA chip was VHDL (very high speed integrated circuit hardware description language). The arithmetic unit implemented has a 32- bit processing unit which allowed limited arithmetic operations such as addition, Subtraction, multiplication and division. The overall coding style used was behavioural modelling synthesis and simulations were done and observed in Xilinx 14.7 and modelsim SE 6.4 version respectively. The final outcome of project revealed that proposed arithmetic unit was able to handle maximum frequency of 126.004 MHz (i.e. Minimum period of 7.936ns).

An arithmetic logic unit (ALU) is a digital electronic circuit that performs arithmetic and bitwise logical operations on integer binary numbers.
This is in contrast to a floating-point unit (FPU), which operates on floating point numbers. It is a fundamental building block of many types of computing circuits, including the central processing unit (CPU) of computers, FPUs, and graphics processing units.
A single CPU, FPU or GPU may contain multiple ALUs
History Of ALU:Mathematician John von Neumann proposed the ALU concept in 1945 in a report on the foundations for a new computer called the EDVAC(Electronic Discrete Variable Automatic Computer
Typical Schematic Symbol of an ALU:A and B: the inputs to the ALU
R: Output or Result
F: Code or Instruction from the
Control Unit
D: Output status; it indicates cases
Circuit operation:An ALU is a combinational logic circuit
Its outputs will change asynchronously in response to input changes
The external circuitry connected to the ALU is responsible for ensuring the stability of ALU input signals throughout the operation

Adders are one of the most widely digital
components in the digital integrated circuit design and are the
necessary part of Digital Signal Processing (DSP) applications.
With the advances in technology, researchers have tried and are
trying to design adders which offer either high speed, low power
consumption, less area or the combination of them. The addition
of the two bits is very Based on the various speed-up schemes for
binary addition, a comprehensive overview and a qualitative

• ALU stands for: Arithmetic Logic Unit.
ALU is a digital circuit that performs
Arithmetic (Add, Sub . . .) and Logical
(AND, OR, NOT) operations.
• John Von Neumann proposed the ALU in
1945 when he was working on EDVAC.

7. Carry Save Adder:
• The basic CSA (carry save adder) is similar to the full
adder but the architecture is different.
• The operation and the principle of CSA is based on
formulae
A + B + C= SUM+2*CARRY
SUM=(A+B+C)mod2 and COUNT=((A+B+C)-
SUM)/2)
• For example if we add three numbers
X=0101,Y=0011,Z=0100.
• Sum=0010 and Saved Carry= 1010 was calculated in
CSA and next in the carry look adder/ ripple carry
adder the output new sum= 1100 and here new carry
is 0.
