DESIGN OF FLOATING POINT MULTIPLIER
Representation of Floating Point Number Decimal Number: -7.5 1 10000001 11100000000000000000000 Sign Exponent Mantissa(Significand)
Why Floating Point???  It can support a much wider range of values as compared to fixed point.  As compared to Integer, Floating Point is more precised.
How to Multiply??  Adding the exponent of the two numbers then subtracting the bias from their result.  Multiplying the significand of the two numbers.  Calculating the sign by XORing the sign of the two numbers.
Block Diagram of Floating Point Multiplier
SIGNIFICAND MULTIPLICATION Multiplication of Significand is done in two steps: 1. Partial Product generation 2. Accumulation of generated Partial Products.
PARTIAL PRODUCTS GENERATION Partial Products generation can be done by various methods, but Radix-4 Booth Multiplication is one of the best technique xi xi-1 xi-2 Operation 0 0 0 +0 0 0 1 +A 0 1 0 +A 0 1 1 +2A 1 0 0 -2A 1 0 1 -A 1 1 0 -A 1 1 1 +0
ACCUMULATION OF PARTIAL PRODUCTS Accumulation of Partial products can be done by various adders, such as: 1. Ripple Carry Adder (RCA) 2. Carry Select Adder (CSLA) 3. Carry Look Ahead Adder (CLA) 4. Carry Save Adder (CSA) Carry Save Adder & Ripple Carry Adder are used for Accumulation.
Floating Point Formats Single precision Double Precision Quadruple Precision Computer Memory 4 bytes (32 bits) 8 bytes (64 bits) 16 bytes (128 bits) Sign bit 1 1 1 Exponent Width 8 11 15 Significand Precision 23 52 112

floating point multiplier

  • 1. DESIGN OF FLOATING POINT MULTIPLIER
  • 2. Representation of Floating Point Number Decimal Number: -7.5 1 10000001 11100000000000000000000 Sign Exponent Mantissa(Significand)
  • 3. Why Floating Point???  It can support a much wider range of values as compared to fixed point.  As compared to Integer, Floating Point is more precised.
  • 4. How to Multiply??  Adding the exponent of the two numbers then subtracting the bias from their result.  Multiplying the significand of the two numbers.  Calculating the sign by XORing the sign of the two numbers.
  • 5. Block Diagram of Floating Point Multiplier
  • 6. SIGNIFICAND MULTIPLICATION Multiplication of Significand is done in two steps: 1. Partial Product generation 2. Accumulation of generated Partial Products.
  • 7. PARTIAL PRODUCTS GENERATION Partial Products generation can be done by various methods, but Radix-4 Booth Multiplication is one of the best technique xi xi-1 xi-2 Operation 0 0 0 +0 0 0 1 +A 0 1 0 +A 0 1 1 +2A 1 0 0 -2A 1 0 1 -A 1 1 0 -A 1 1 1 +0
  • 8. ACCUMULATION OF PARTIAL PRODUCTS Accumulation of Partial products can be done by various adders, such as: 1. Ripple Carry Adder (RCA) 2. Carry Select Adder (CSLA) 3. Carry Look Ahead Adder (CLA) 4. Carry Save Adder (CSA) Carry Save Adder & Ripple Carry Adder are used for Accumulation.
