This group is for the discussion of the open-source 32-bit floating point unit (FPU), desgined by Jidan Al-Eryani. It can also be downloaded from opencores.org

 

Features

• FPU supports the following arithmetic operations:
  • Add
  • Subtract
  • Multiply
  • Divide
  • Square Root

• For each operation the following rounding modes are supported:
  • Round to nearest even
  • Round to zero
  • Round up
  • Round down

• Pipelined to achieve high operating frequency (100MHz with Cyclone EP1C6)

• Tested with 2 million test cases

• Hardware proven: FPU was implemented in a Cyclone I–EP1C6 FPGA chip and was then connected to the Java processor JOP (www.jopdesign.com) to do some floating-point calculations.

For more details please read the documentation.
