2.1.6 DSP function instructions
The DSP function instructions carry out multiplication of 32 bits x 16 bits and 16 bits x 16
bits or multiply and add operation; there are also instructions to round off data in the
accumulator and carry out transfer of data between the accumulator and a general-
purpose register.
MACHI Multiply-accumulate high-order halfwords
MACLO Multiply-accumulate low-order halfwords
MACWHI Multiply-accumulate word and high-order halfword
MACWLO Multiply-accumulate word and low-order halfword
MULHI Multiply high-order halfwords
MULLO Multiply low-order halfwords
MULWHI Multiply word and high-order halfword
MULWLO Multiply word and low-order halfword
MVFACHI Move high-order word from accumulator
MVFACLO Move low-order word from accumulator
MVFACMI Move middle-order word from accumulator
MVTACHI Move high-order word to accumulator
MVTACLO Move low-order word to accumulator
RAC Round accumulator
