Design Example: Floating-Point Converter

Binary floating-point arithmetic is commonly used to represent real numbers on computers because it can represent a wide range of numbers. When implemented in FPGAs, however, floating-point can use considerable logic resources. Therefore, designers use fixed-point because of its better performance and lesser resource utilization. Essentially, a floating-point number is converted to a fixed-point before an operation. The result is then converted back to a floating-point for compatibility with other systems.

Efinix provides example design that demonstrates the conversion between floating-point and fixed-point numbers. The design targets the Titanium Ti60 F225 Development Board and TrionĀ® T120 BGA576 Development Board. The example design includes Efinity Virtual I/O Debugger core for customizing and monitoring the design.
