C6455 IQmath execution cycle

weslly li

Hi,

I'm trying to use IQmath functions in C6455. From benchmark of the user guide, some of them should consume only a few cycles, but when i run them in simulator, they consume many more cycles than benchmark. And i really put everything in L1-SRAM.

Anyone can help me out please?

Weslly,

Do you have the full source for the IQMATH library? The benchmarking was done using full inlined source which might be the reason for the mismatch. You can request the source here:

Let us know if this takes a while to get approved.
