In the HRM of the BF609: the ACU support maximum operation ( (output = max(input1,input2) ) (
One arithmetic unit (ACU) supporting 32-bit arithmetic operations (product, sum, accumulation,
shift, maximum, minimum).)
But in the registers settings:
1-PVP_ACU_CFG : ACU Configuration
2-PVP_ACU_CTL : ACU Control
No option to support this feature (maximum operation), any idea how to configure ACU for maximum feature (output = max(input1,input2) ???
