Multiply sources into destination.
The following modes are supported:
u32 * u32 -> u64[31:00] u32 * s32 -> s64[31:00] s32 * u32 -> s64[31:00] s32 * s32 -> s64[31:00] u32 * u32 -> u64[63:32] u32 * s32 -> s64[63:32] s32 * u32 -> s64[63:32] s32 * s32 -> s64[63:32]
Extended-precision multiplications are performed using the IMAD instruction instead of the IMUL instruction.
