The following is a block diagram of RXAAL:
RXAAL Block Diagram
RXAAL performs the cell and packet reassembly functions. This includes the AAL processing and moving cell
data and packet headers to Packet Memory.
The nano-program uses state and configuration informations from the LCD cache to perform the necessary
function for each cell. The nano-processor is capable of executing programs to run the following types of
reassembly:
RXAAL also performs the cell/packet post processing step. This includes event generation to RXQUE, cut
through processing, scatter processing, and DMA enqueues.
