double precision floating-point (float32), integer doubleword(int32), double precision floating-point (float32), integer doubleword(int32), double precision floating-point (float32), integer doubleword(int32), double precision floating-point (float32), integer doubleword(int32), double precision floating-point (float64), integer quadword (int64). Therefore, a ZMM vector register can hold 8, 16, 32,
