Programmable Real-time Unit (PRU) 1. What is PRU? – Programmable Real-time Unit Subsystem – Dual 32bit RISC processors running at ½ CPU freq. – Local instruction and data RAM. Access to chip-level resources 2. Why PRU? – Full programmability allows adding customer differentiation – Efficient in performing embedded tasks that require manipulation of packed memory mapped data structures – Efficient in handling of system events that have tight real-time constraints.
PRU Value 1. 2. 3. – – – – – – 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) 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.
