Abstract
In the L2 FIFO architecture incoming frames are stored in a multi bank FIFO to enable offloading the programmable real-time unit to do other tasks. The L2 FIFO buffers data coming from the L1 FIFO, reducing the polling time for received data. Status is always checked for errors before processing the data and updating the state variables. Implementing a state machine to perform some of the checks results in a PRU utilization that is not a function of the bytes that need to be processed.
