Embodiment 1

[0037] like Figure 1 to Figure 5 As shown, the present invention adopts Zynq 7000 series products of Xilinx, and the hardware architecture is composed of ARM (PS) + FPGA (PL), wherein the ARM architecture adopts dual-core hardened Cortex-A9 microprocessor. Based on the dual-core hardware platform of Zynq 7000 series, the present invention designs a set of wireless signal PS dual-core processing software architecture in combination with the wireless signal processing method.

[0038] The invention is based on Zynq 7000 hardware, and the PL side continues to use the reliable FPGA algorithm for digital processing of wireless signals in recent years, which ensures the stability and reliability of the software framework. Although FPGA is a field programmable logic gate array, compared with ASIC development, the development cycle is shortened and the hardware cost is reduced. However, for a relatively large software project, for the modification of the FPGA code, it is necessary t...

Embodiment 2

[0050] like Figure 1 to Figure 5 As shown, as a further optimization of Embodiment 1, this embodiment includes all the technical features of Embodiment 1. In addition, this embodiment also includes the following technical features:

[0051] Reception: The wireless signal received by the wireless channel antenna is converted by AD, and the data is transferred to the PL, and the signal processing process such as demodulation is completed in the PL. The ARM0 of the PS will process the data for protocol processing, and interrupt 0 will be generated. Enter the serial port of the PL non-wireless channel peripheral. Further, the wireless signal received by the wireless channel antenna undergoes AD conversion, and the data is transferred to the PL. Signal processing such as demodulation is completed in the PL, and the data is stored in the BRAM1, and the PS takes out the BRAM1 data for corresponding processing.

[0052] Send: The original data with transmission is sent to the PL thr...

Abstract

The invention relates to the technical field of communication signal transmission and processing, and discloses a wireless signal processing method based on an all-programmable on-chip system. In the method, when receiving data processing, first use PL to obtain external wireless signals and analyze the obtained external wireless signals. The wireless signal is digitally processed, and then the digital signal-processed data is transmitted to the PS, and then the PS is used to obtain the signal transmitted by the PL and perform protocol processing; Original data, then transmit the original data to PS, then use PS to obtain the signal transmitted by PL and perform protocol processing on the data to be sent, then transmit the data to be sent after the protocol processing to PL, and finally use PL to send the data to be sent. . The invention solves the problems existing in the prior art, such as complex equipment, large system volume, high power consumption, poor flexibility, and poor system stability.

Description

technical field [0001] The invention relates to the technical field of communication signal transmission and processing, in particular to a wireless signal processing method based on a fully programmable system-on-chip. Background technique [0002] SoC (System on Chip) is called a system-on-chip, also known as a system-on-chip. Xilinx's Zynq7000 series is a commonly used all-programmable system-on-chip, which mainly includes PS (processingsystem) and PL (ProgrammableLogic). The Zynq 7000 series scalable processing platform tightly integrates the processing system (PS) of the dual-core ARMCortex-A9MPCore processor and the programmable logic (ProgrammableLogic, PL) system of programmable logic resources.
