Seems to be a (over)simplified variant of pi32v2, which even lacks some features of pi32..
Between q32s and pi32/pi32v2, the differences are:
16 general purpose registers, r0 through r15.
Unlike pi32v2, there isn’t any “doubled” registers (r0_r1 - r14_r15),
as well as any associated operations like multiply-accumulate operations and alike.
