if you are on RP2040 then i would expect the in64_t performance (particularly DIV) to be better with SDK (unless Arduino is also correctly setting up to use the h/w divider) - that said i'm only "expecting" thatI assumed that arduino-pico and C sdk use the same compiler. That's why I was surprised to see 2x speed difference in calculation, but if it is not, that may explain the difference, though that may also suggest C sdk needs better int64 emulation.
can someone post some DIS files on RP2040 for Arduino and SDKStatistics: Posted by kilograham — Fri Jan 10, 2025 9:16 pm
