Function core::arch::x86_64::_tile_dpbf16ps

pub unsafe fn _tile_dpbf16ps(const DST: i32, const A: i32, const B: i32)

🔬This is a nightly-only experimental API. (x86_amx_intrinsics #126622)

Available on x86-64 and target feature amx-bf16 only.

Compute dot-product of BF16 (16-bit) floating-point pairs in tiles a and b, accumulating the intermediate single-precision (32-bit) floating-point elements with elements in dst, and store the 32-bit result back to tile dst.
