How do you represent a floating point in Verilog?

How do you represent a floating point in Verilog?

Floating points are stored using a mantissa and exponent. They can represent a much wider range of values, but are more complicated to manipulate.

What is floating point arithmetic operations?

Arithmetic operations on floating point numbers consist of addition, subtraction, multiplication and division. The operations are done with algorithms similar to those used on sign magnitude integers (because of the similarity of representation) — example, only add numbers of the same sign.

How do you find the bias of a floating point?

To calculate the bias for an arbitrarily sized floating-point number apply the formula 2k−1 − 1 where k is the number of bits in the exponent. When interpreting the floating-point number, the bias is subtracted to retrieve the actual exponent. For a single-precision number, the exponent is stored in the range 1 ..

What is real in Verilog?

real is typically a 64 bit IEEE floating point number. realtime is of type real used for storing time as a floating point value. reg is by default a one bit unsigned value. The reg variable data type may have a modifier signed, and may have may bits by using the vector modifier [msb:lsb].

How do you convert to floating point?

Converting a number to floating point involves the following steps:

1. Set the sign bit – if the number is positive, set the sign bit to 0.
2. Divide your number into two sections – the whole number part and the fraction part.
3. Convert to binary – convert the two numbers into binary then join them together with a binary point.

How do you perform arithmetic with floating point numbers?

Addition and Subtraction

1. Step 1: Represent the first number with an exponent.
2. Step 2: Represent the second number with the same exponent as the first number.
3. Step 3: Add the two numbers.
4. Step 4: Results.
5. Step 1: Perform the Multiplication.
6. Step 2: Rounding.
7. Step 3: Normalizing.

What is the best way to represent floating point numbers in Verilog?

You should see the Qn.m format which is usually I believe is the best possible way for the representation of floating numbers in verilog. For more help, you could possibly use the articles related to 32-bit floating point adder or multiplier. Try google that.

What is the IEEE 754 standard size for floating point multiplication?

Normalization Overflow, underflow Rounding Floating point addition Floating point multiply Floating Point (IEEE-754) use a fixed number of bits Sign bit S, exponent E, significand F Value: (-1)Sx F x 2E  IEEE 754 standard Size Exponent Significand Range Single precision 32b 8b 23b 2×10+/-38

What are the basic requirements for floating point arithmetic?

As far as floating point arithmetic is concerned, you have to design your own architecture with compliance to IEEE 754 standard as mentioned earlier. Just take care of exponent, mantissa, sign bit, single precision or double precision.
