Expand description

Compute dot-product of FP16 (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. The shape of the tile is specified in the struct of __tile1024i. The register of the tile is allocated by the compiler.
