The QorIQ Data Path Acceleration Architecture or QorIQ DPAA is a architecture which integrates aspects of packet processing in the SoC, thereby addressing issues and requirements resulting from the multicore nature of QorIQ SoCs. The DPAA includes Cores, Network and packet I/O as well as hardware offload accelerators.
The DPAA can be used to address various performance related requirements, especially those created by the high speed network I/O found on multicore SoCs such as the P4080.
