signed 8-bit * signed 8-bit VNNI

[lin__chiungliang]

Hi,

I'm trying to use VNNI in my program.

I ran the sample code, which do MAC operation by _mm512_dpbusds_epi32,

I found that it's singed 8-bit and unsigned 8-bit operation

Does there any optimized instruction support

1. signed 8-bit and signed 8-bit MAC operation

2. unsigned 8-bit and unsigned 8-bit MAC operation

Lot of thanks

Hi chiungliang

sorry for late response.

this question is more related to general compiler issue, and it would be better to let our compiler experts to answer this question.

This forum can help on DL libraries and framework related questions, but you should get better support for intrinsic programming in compiler forum.

Would you mind posting the same question in below forum?
