Freescale Semiconductor 4) Host Memory region for transmit buffers, memory mapped over PCIe on the adapter and translated via outbound ATMU. 5) Mapping memory regions - Host to QorIQ memory region using inbound ATMU, QorIQ to Host memory region using outbound ATMU. 6) Control flow between various components like FMAN, QMAN, BMAN, Linux Core on QorIQ and Host. 7) Usage of Command ring from Host to send commands to P4080 which are processed by Core 1 on P4080. These are forwarded to corresponding Hardware Function library on P4080. 8) API exposed by Host Packet Driver and P4080 Packet Driver library. © Freescale Semiconductor, Inc., 2011.
