double vector format support

Jump to solution

Hi all,

I was trying to rewrite / cleanup my kernel by replacing all unrolled for-loops by vector calculations.
However, during compilation I receive the following error:

   use of undeclared identifier 'double4'; did you mean 'double'?

According to the OpenCL Documentation, double4 is supported when using "#pragma OPENCL_EXTENSION cl_khr_fp64 : enable". Which is present in my code, as it works without issues with double precision variables in unrolled loops.

So, does SDAccel support the doubleN format?
And would the use of vector formats have any performance or area benefit over unrolled loops?

Kind regards,
Remy
