8 years agoThis is in fact a very useful comment. Indeed the DSP utilization and performance without the pragma is higher which suggests the loop might have been unrolled by the compiler. With pragma though, the LEs and FFs utilization increases (and DSP utilization decreases) for the kernel A which made me think that it was now using logic instead of DSP for the arithmetic computations. I do not have a break down of resource utilization for different sections of the kernel to confirm any theory. I will try to explore this more.
