pub unsafe fn _tile_dpbf8ps(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-fp8 only.Expand description
Compute dot-product of BF8 (8-bit E5M2) floating-point elements in tile a and BF8 (8-bit E5M2) floating-point elements in tile 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.
