sinf.c vs v_sinf.c #49

Closed godmiaozi closed 1 year ago

godmiaozi commented 1 year ago

what is the difference between sinf and v_sinf?
why do we have two different implementation for sinf?
which one is faster?

v_sinf is the vector version that computes 4 results at a time, so it's suitable for vectorized code. Generally vector versions have worse accuracy and higher latency but significantly more throughput.
