load_matrix_b_amd

load_matrix_b_amd[m: Int, n: Int, k: Int](b_ptr: UnsafePointer[SIMD[float32, 1]], tile_row: Int, tile_col: Int, ldm: Int) -> SIMD[float32, 1]

Loads a tile of matrix B from memory to registers for AMD FP32 tensor core operations.

Parameters:

  • ​m (Int): Number of rows in the output matrix tile.
  • ​n (Int): Number of columns in the output matrix tile.
  • ​k (Int): Inner dimension for matrix multiplication.

Args:

  • ​b_ptr (UnsafePointer[SIMD[float32, 1]]): Pointer to matrix B data in memory.
  • ​tile_row (Int): Starting row index of the tile.
  • ​tile_col (Int): Starting column index of the tile.
  • ​ldm (Int): Leading dimension of matrix B (stride between rows).

Returns:

SIMD vector containing 1 FP32 value loaded from matrix B.
