  A domestic hardware platform based on MTCA.4 is developed for a single cavity regulation in Southern Advanced Photon Source Test Platform (SAPS-TP). A multifunction digital processing Advanced Mezzanine Card (AMC) works as the core function module of the whole system, implement high speed data processing, Low-Level Radio Frequency (LLRF) control algorithm and interlock system. Its core data processing chip is a Xilinx ZYNQ SOC, which is embedded an ARM CPU to implement EPICS IOC under embedded Linux. A down-conversion and up-conversion RTM for cavity probes sensing and high power RF source driver can communi-cate with AMC module by a ZONE3 connector. A hosted tuning control FPGA Mezzanine Card (FMC) combines both the piezo controlling and step-motor controlling functions for independent external drive devices. The design of the hardware and software of the platform electronics and some test results are described in this paper. Further test and optimization is under way.
