Is there a list available of the math library functions that are supported by CoDeveloper?

Is there a list available of the math library functions that are supported by CoDeveloper?

Hi,
Presently there is not a list because there is not really a math.h library to speak of. As soon as a library becomes available per supported vendor, associated documentation will be provided with each release.

As of 3.20.b.6, the following floating-point operations are supported using functions of the same name, when using any Xilinx or Altera platform:

• sqrt (Xilinx only)
• sqrtf (single-precision, Xilinx only)
• fabs
• fabsf (single-precision)
• All standard C arithmetic operators and type conversions involving float and double types

Other floating-point math operations are supported by primitive functions or processes written in Impulse C and found in various examples distributed with the CoDeveloper release:

Example: BlackScholes_double

• log (my_log)
• exp (my_exp)

Example: CordicMath

• fabs (myfabs)
• sqrt (mysqrt)
• sin (sin64)
• exp (exp64)

Example: Cordic_Sine

• sin (sin64)

Integer square root is also available in two examples:

Example: SquareRoot

• 32-bit sqrt (isqrt)

Example: SquareRoot8bit

• 8-bit sqrt (mySqrt)

This is not an exhaustive list; it does not include examples of math functions not part of the standard C math library, such as FFTs, FIR filters, or CRCs, that ship as example projects with the CoDeveloper release, or as Ready-to-Run examples available for download.

Thanks Ralph,

I wasn't aware of the functions in the BlackScholes example
