Multiply instructions
Table 8-1.
These instructions require one pass through the multiplier array and produce a 32- or 48-bit
result. For mulrndhh, a rounding value of 0x8000 is added to the product producing the final
result. This group does not set any flags, except for the mulsat instructions which set Q if satura-
tion occurred.
Table 8-2.
