DSP Library – 

Provides a wealth of popular DSP operation 

including FFTs, filters, vector math and matrix math.

Flash API and Boot ROM Utilities

  IQMath Library
 

A library and compiler intrinsic that allows you to select  

 

  your range and resolution by choosing which bits of  
  your binary represented number are integer (I) and which  

 

  are the quotient (Q). It also allows you to write C functions in 
  floating point format instead of dealing with fixed-point scaling,   
  and the compiler takes care of the rest.

Basic math operations such as trigonometry 

issued across three sets of libraries – optimized for fixed-point, 
floating-point or the Control Law Accelerator (CLA).

Specialized, application specific software functions 
• Modular macros with variable inputs and outputs
• At initialization all variables are defined and outputs of
  one block are set as inputs to the next
• Complete documentation – including source code, use
  and technical theory – is provided for every module

//initialization code, define macro per library

#define PARK_MACRO(v)
v.Ds = _IQmpy(v.Alpha,v.Cosine) + _IQmpy(v.Beta,v.Sine);
v.Qs = _IQmpy(v.Beta,v.Cosine) - _IQmpy(v.Alpha,v.Sine);

//incremental build code, connect outputs and inputs

park1.Alpha = clarke1.Alpha;
park1.Beta = clarke1.Beta;

//run-time code, call  the function

PARK_MACRO(park1)
