Floating Point Megafunctions

Many modern digital signal processing (DSP) systems employ floating-point functionality to achieve the high degree of numeric precision and dynamic range that most applications require. Applications such as radar, sonar, bioscience and molecular science, financial modeling, advanced wireless antenna processing, medical imaging, image analytics and synthesis and precision control are just a few applications that are creating a demand for floating-point capabilities in FPGAs. Furthermore, as FPGAs continue to grow in size and capability, they are becoming the highest performance platform available for any type of floating-point-based algorithm or computation.

Altera provides the largest library of IEEE 754-compliant floating-point megafunctions, and they can all be used in any Altera® device family. Key megafunctions include:

* Addition/subtraction [altfp_add_sub]
* Multiplication [altfp_mult]
* Division [altfp_div]
* Square root [altfp_sqrt]
* Compare [altfp_compare]
* Logarithm [altfp_log]
* Exponential [altfp_exp]
* Inverse [altfp_inv]
* Inverse square root [altfp-inv_sqrt]
* Matrix multiplier [altfp_matrix_mult] (New with v 9.0)
