Floating point to fixed point and vice versa in verilog

[dean07]

hi...i currently working mu final project that would need me to use this conversion. Here what i'm trying to do:

1. let say i have this number in decimal 6.23456. I want to multiply this value with other value (integer) and display the result ( in fraction num) on seven segment using verilog code.

for example:

value a=6.23456
value b=6

c=a*b

by calculation...c=37.40736. How do i display this value on seven segment display. I'm using Altera DE2-70 board.

hi
you need to code a multiplier and a decimal to seven segment interface,to achieve this.

As dll_fpga said you need a floating point or fixing point multiplier ,

Altera Offers a floating point multiplier

otherwise there are some free cores

This generator allows you to customize a multiplier to meet your own design needs.
This is the full set of Verilog code for the multiplier. It has been verified as a working floating-point
