This section describes the MAC (multiplier with accumulation) module integrated to PRU0/PRU1 cores.
Each of the two PRU cores (PRU0/PRU1) has a designated unsigned multiplier with accumulation (MPY/MAC). The MAC supports two modes of operation: Multiply Only and Multiply and Accumulate.
The MAC is directly connected with the PRU internal registers R25-R29 and uses the broadside load/store PRU interface and XFR instructions to both control and mode of the MAC and import the multiplication results into the PRU.
The PRU MPY/MAC features are:
