20:21 <_whitenotifier-f> [amaranth] whitequark opened issue #1349: Add `AMDPlatform`, aliasing `XilinxPlatform` - https://github.com/amaranth-lang/amaranth/issues/1349

20:37 mcc111[m] has joined #amaranth-lang

20:37 <mcc111[m]> Slightly offtopic question but: Should I expect vexiriscv-smp to be significantly slower when doing modulo operations than when doing multiplications?

20:37 <mcc111[m]> assume these modulos are probably not powers of two.

20:38 <whitequark[cis]> yes

20:38 <whitequark[cis]> divmod is probably some of the slowest operations you can get a modern CPU to execute, even on desktop x86

20:39 <mcc111[m]> Thanks

21:30 <cr1901> mcc111[m]: From taking a quick look at VexRiscv's main division loop, it looks like you can speed up its latency/throughput by increasing divUnrollFactor: https://github.com/SpinalHDL/VexRiscv/blob/457ae5c7e5c8183f0ba7c51f7f0301d05eb8ced1/src/main/scala/vexriscv/plugin/MulDivIterativePlugin.scala#L135-L151

21:32 <cr1901> (The division loop "looks like" one I wrote for a divider recently, except mine has a fixed latency/throughput of "32" if you want a RISCV-compat divider: https://github.com/cr1901/smolarith/blob/next/src/smolarith/div.py#L488-L505)
