The Floating Point Operator IP core provides the user with the means to perform floating point arithmetic on Xilinx® Field Programmable Gate Arrays (FPGAs). The operation is specified when the core is generated, and each operation variant has a common interface. The DO-254 Floating Point Operator allows converts from floating point to fixed point and fixed point to floating point.
Key features are:
- Supports the following operators:
- Multiply
- Divide
- Add
- Conversion from floating-point to fixed-point
- Conversion from fixed-point to floating-point
- Comparison (greater than and less than)
- Compliance with IEEE-754 Standard
- Parameterized fraction and exponent wordlengths for most operators
- Optimized for speed
- Fully synchronous design using a single clock
Documentation
The COTS version v7.0 is the baseline from which the DO-254 Floating Point Operator 1.10a comes from. Logicircuit applies the DO-254 lifecycle to this COTS version. As a result of this DO-254 process, the source code will be modified with the goal of achieving 100% code coverage, and the resulting code will be named DO-254 Floating Point Operator 1.10a. Below are links to the Xilinx® Product Data for the version that was used as the basis, and the Logicircuit Data Sheet of the resulting DO-254 product.
