WB_FPU - Wishbone Floating Point Unit
Figure 1. WB_FPU - Wishbone Floating Point Unit.
Altium Designer's floating-point unit - WB_FPU - facilitates the conversion of 32-bit integer values into single precision floating-point numbers, and vice-versa. This hardware peripheral performs these conversions and additional, standard mathematical calculations, with greater speed when compared with previous, software-based floating-point support.
Incorporating the standard Wishbone interface, the WB_FPU can be used with any of the 32-bit processors available in Altium Designer.
Features at-a-glance
- Converts 32-bit integer values to single precision floating-point numbers, in accordance with the IEEE-754 standard
- Converts single precision floating-point numbers to 32-bit integer values
- Perform addition of two single precision floating-point numbers
- Perform subtraction of two single precision floating-point numbers
- Perform multiplication of two single precision floating-point numbers
- Perform division of two single precision floating-point numbers
- Wishbone-compliant.
