Actually I want the IPC(Instruction per Clock Cycle) value for VisionFive2 board, If anyone knows please give the reply.
The U74-MC is SiFive IP, so according to their website it is a “Dual Issue, in-order 8 stage Harvard Pipeline”, so I would guess that the very worst case (bad L1 and L2 cache hits) would be about ~1.6 IPC (Instructions Per Cycle) per core (Technically there are 5 cores in the U74-MC, but only 4 are used under Linux and there is also a currently unused E24 in the VF2 SoC. But the E24 would be Single issue.).
I guess under Linux you could claim a worse case total IPC of 6.4 (4x U74 cores). And if you were bare metal programming using all 6 cores you could probably claim an IPC of 9 with the VF2 hardware. But I am only guessing here. The E24 is asynchronous and has a much lower clock rate so the worse case IPC is probably lower than 9 for the whole JH7110 SoC.
Please refer to chapter 3.3
S7 Execution Pipeline and 4.3
U7 Execution Pipeline of this spec. You most likely don’t care about S7, which is currently unused.
You can also figure out the runtime performance through
mcycle means absolute number of clock cycles and
minstret means absolute number of instruction retired.
