Occasional ContributorDoing low bit-width fixed precision FMA on DSP in OpenCL
The appropriate IP Core is either directly used by the OpenCL compiler, or eventually employed by the mapper depending on the width of your variables. I remember there were some topics in the forum about this subject before and the compiler's behavior was kinda buggy, though. You can also take a look at the variable-width integer extension and the instructions for correctly inferring fixed-point arithmetic in the Best Practices Guide.
