PRU Value
1. Extend Connectivity and Peripheral capability
– Implement special peripherals and bus interfaces (e.g. UARTs)
– Implement smart data movement schemes. Especially useful for – Implement smart data movement schemes. Especially useful for
Audio algorithms (e.g. Reverb, Room Correction)
2. Reduce System Power Consumption 2. Reduce System Power Consumption
– Allows switching off the ARM clocks
– Implement smart power controller by evaluating events before
waking up ARM. Maximized power-down time. waking up ARM. Maximized power-down time.
3. Accelerate System Performance
