Small Cell Baseband Solution
The Zynq™-7000 All Programmable SoC devices are well suited for designing small cell base stations ranging from femtocell to metrocell. The on-chip dual ARM Cortex™ A9 processors address the real-time processing tasks: one Cortex-A9 manages Layer 1 control, DDP coefficient calculation and the RTOS while the other Cortex-A9 runs part or all of the higher-layer functions.
The FPGA fabric can be used to accelerate Layer 2 functions, thus offloading the ARM processors to provide designers with more flexible acceleration options. On-chip logic enables the integration of DFE functions (DUC/DDC, CFR and DPD IP), which contributes to further reduction in power consumption while reducing end-to-end latency. The integrated PCIe connectivity enables seamless integration of Wi-Fi for data offloading.
