Embodiment 1

[0018] A wireless data processing system based on a DSP processor, including a DSP processor, an analog-to-digital converter, a PC and a wireless device, the DSP processor and the analog-to-digital converter are connected to each other through an FPGA module, and the DSP processor and the FPGA module are based The core of the system mainly completes the control of the analog-to-digital converter and the processing of data, which has the characteristics of large amount of collected data, fast speed and high precision; the PC is connected to the DSP processor through a wireless device, and the FPGA module A JTAG interface is provided, and the analog-to-digital converter is connected with an analog signal conversion device, wherein the analog signal conversion device mainly implements buffering, amplification, attenuation and filtering of the analog signal to obtain the signal required by the analog-to-digital converter; The analog signal conversion device is connected with a sens...

Embodiment 2

[0021] This embodiment is further optimized on the basis of the above embodiments, such as figure 1 Shown, further for realizing the present invention better, adopt following setting structure especially: described FPGA module is also connected with SDRAM, power supply circuit; Described DSP processor is connected with memory and power supply, and wherein FPGA module can change flexibly Signal frequency, and then change the sampling frequency of the system, so the analog-to-digital converter is provided by the FPGA module, and the FPGA module also provides signals for the analog-to-digital converter, which triggers the DSP interrupt through the FPGA module. After the analog-to-digital conversion, the FPJA module reads the conversion result into SDRAM. The data converted by the analog-to-digital converter is stored in SDRAM through the FPJA module.

Description

technical field [0001] The invention relates to the technical field of data processing, specifically, a wireless data processing system based on a DSP processor. Background technique [0002] The data acquisition system started in the 1950s. Because the data acquisition and testing system has high speed and certain flexibility, it can meet many data acquisition and testing tasks that cannot be completed by traditional methods, so it has been initially recognized. In the mid-1970s In the later stage, in the development process of data acquisition system, it is gradually divided into two categories, one is laboratory data acquisition system, and the other is industrial field data acquisition system; with the popularization and application of computers, data acquisition system has been greatly developed. Gradually common data acquisition and automatic test systems appear. [0003] Now, with the development of electronic technology, high-speed data acquisition technology is wid...
