Hi Roger,
Sorry , I forget to update examples to rvv 0.9 include removing vector c operator,
thanks for point out, I will update it soon.
sgemm example is translated from rvv spec example without loop unrolling, you can reference below diagram to understand the code.
Thanks.

Hi @zakk0610,
thanks for the prompt answer. Definitely I was mistaken with the sgemm.
Kind regards,

Hi @zakk0610,
some extra comments in the hope they're useful.
-void sgemm_golden() {
+void sgemm_golden(void) {
for (size_t i = 0; i < MLEN; ++i)
for (size_t j = 0; j < NLEN; ++j)
for (size_t k = 0; k < KLEN; ++k)
- c_array[i * NLEN + j] += a_array[i * KLEN + k] * b_array[j + k * NLEN];
+ golden_array[i * NLEN + j] += a_array[i * KLEN + k] * b_array[j + k * NLEN];
}
int main() {
// golden
- memcpy(golden_array, b_array, OUTPUT_LEN * sizeof(float));
- sgemm_golden(MLEN, NLEN, KLEN, a_array, KLEN, b_array, NLEN, golden_array, NLEN);
+ sgemm_golden();
// vector
- memcpy(c_array, b_array, OUTPUT_LEN * sizeof(float));
sgemm_vec(MLEN, NLEN, KLEN, a_array, KLEN, b_array, NLEN, c_array, NLEN);
With these changes (along with those of the load/store) this sgemm test passes in our emulator.
Thanks!

Thanks @rofirrim!
I fixed them and they can also passed in spike simulator now.
