Texas Instruments TI SITARA manual PRU Value, Extend Connectivity and Peripheral capability

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 Audio algorithms (e.g. Reverb, Room Correction)

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.

3.Accelerate System Performance

–Full programmability allows custom interface implementation

–Specialized custom data handling to offload ARM for innovative signal processing algorithm implementation
