    99FPGA framework architecture for Zynq based platforms is as shown below. Main blocks of the framework are
    10 1) Processor subsystem - Signle ARM Cortex A9 core is being used with dual AXI bus architecture, AXI0 for Ehternet/IP packet traffic, and AXI1 for all the other data such as hardware configuration, system control and monitoring.
    11 2) Ethernet processing - provides Ethernet packing/unpacking functionality, and integration with AXI bus architecture. Since GigE MAC resides within the embedded CPU sub-system, DMA is therefore is used to transfer incoming and outgoing traffic between Framework and GbE MAC module. Note that the processor is not invoked for this type of data transfers; it is only used to setup the DMA transaction descriptors.
    12 3) Packet Processor - simple packet classification/forwarding scheme based on IP/UDP. Control packets get routed to the processor core, where as data packets are forwarded to corresponding APP for further wireless layer processing. It supports a subset of VITA Radio Transport protocol.
    13 4)RMAP Processor - general sub-system interfacing and control, provides processor interfacing and address decoding.
    14 5)APP design space - integrates two presumably orthogonal design spaces into a full working system.
