AI summary
An example system-on-chip (SoC) device for a communication system includes a peripheral component interconnect express (PCIe) interface configured to receive data from a backhaul field programmable gate array (FPGA) of the communication system, and a producer port linked with a consumer port through direct memory access (DMA). Data received by the PCIe interface is assigned to the producer port. The device includes dual hardware media access controls (MACs) configured to consume the data assigned to the producer port, and at least one processor configured to supply the data to a wireless interface for transmission to another wireless communication device of the communication system at a frequency of at least sixty Gigahertz.
