Embodiment 1

[0037] Such as Figure 1 to Figure 6 As shown, compared with the traditional CPLD, FPGA has the advantages of shortened development cycle, simplified logic, and lower cost for wireless signal processing. Among them, Xilinx Zynq 7000 series (preferably Zynq 7000) products integrate the processing system (Processing System, PS) of the dual-core ARM-Cortex-A9 MPCore processor with the programmable logic (Pro-grammable Logic, PL) system of programmable logic resources Integrated embedded system hardware design. The present invention is based on the Xilinx Zynq 7000 series platform in combination with signal processing features and Zynq 7000 series platform characteristics to carry out the design of the signal processing architecture, and utilize the respective characteristics of PL and PS to design the wireless signal processing architecture method as follows figure 1 .

[0038] The two BRAMs of the Zynq 7000 series are named BRAM1 and BRM2 respectively. The processing of wirel...

Embodiment 2

[0049] Such as Figure 1 to Figure 6 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:

[0050] Reception: The wireless signal received by the wireless channel antenna is converted by AD, and the data is transmitted to the PL, and the signal processing process such as demodulation is completed in the PL, and the data is stored in BRAM1, and the PS takes out the BRAM1 data for corresponding processing.

[0051] Sending: The original data sent by the belt is transmitted to PL through serial port 1, PL stores the data into BRAM2, PS takes the data out from BRAM2 for corresponding processing, stores the processed data into BRAM1, PL takes out the data of BRAM1 for modulation and other signals Processing, and then the data is processed by DA and sent out. While performing sending processing, PS will control RF commands to be transmitt...

Abstract

The invention relates to the technical field of wireless communication signal transmission and processing of an all-programmable system-on-chip, and discloses a wireless signal processing method and system applying the all-programmable system-on-chip. According to the invention, when the all-programmable system-on-chip carries out received data processing, The method comprises the following steps: firstly, acquiring an external wireless signal by utilizing the PL and performing digital signal processing on the acquired external wireless signal, and then acquiring a signal by utilizing the PS and performing protocol processing on the signal; and when the all-programmable system-on-chip processes transmitted data, using the PL for receiving original data to be transmitted, using the PS for acquiring the data to be transmitted and performing protocol processing on the data to be transmitted, then using the PL for extracting the data to be transmitted and performing digital signal processing, and finally carrying out DA conversion on the data to be transmitted and then sending out the data. The problems of complex equipment, large system size, high power consumption, poor flexibility, poor system stability and the like in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of wireless communication signal transmission and processing, in particular to the technical field of wireless communication signal transmission and processing of an all-programmable system-on-chip, in particular to a wireless signal processing method and system using an all-programmable system-on-chip. Background technique [0002] SoC (System on Chip) is called a system-on-chip, also known as a system on a chip. Xilinx's Zynq7000 series products are a commonly used fully programmable system on a chip, which mainly includes two parts: PS (processing system) and PL (Programmable Logic). The Zynq 7000 series scalable processing platform tightly integrates the processing system (ProcessingSystem, PS) of the dual-core ARM Cortex-A9MPCore processor and the programmable logic (ProgrammableLogic, PL) system of programmable logic resources, achieving higher flexibility and scalability. Embedded system hardware desi...
