How to use extended precision state memory for SigmaStudio for Griffin4.1.0

Hi,

I'd like to use  extended precision state memory with plugin for algorithm designer in SigmaStudio for Griffin..

Considering it very simply, I think that if I use the following two lines,

the variable(peState is reference to extended precision) state memory will be extended precision.

 

float *peState;

peState   = &(pBlkAlgoInfo->pExtPreState[0]);

Need any pragmas for extended precision?

Thanks and Regards,
