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 ve tight

real-time constraints.
