怎么将FPGA用作无线射频模块的简单预处理器

你好，
我正在寻求帮助，为相当简单的应用选择合适的FPGA。
我想将FPGA用作无线射频模块的简单预处理器。
主要目的是在传输到无线模块之前抽取过采样数据。
具体来说，我需要FPGA来执行以下功能：
（1）接收多通道数字数据 - 有16个数据通道通过SPI串行接口进入FPGA。
数字数据被过采样（10kHz采样率）。
每个样本16位。
（2）将多通道数据抽取/下采样4倍（可能使用CIC滤波器，或CIC + FIR补偿滤波器或多相）。
（3）通过并行接口或可能通过SPI将下采样数据传输到无线模块。
（4）可能需要在输入端（抽取之前）和/或输出端（在抽取之后，在传输到无线模块之前）使用FIFO缓冲器。
是否建议Xilinx FPGA器件适合该应用？
另外，是否有推荐的方法来估算所需的门数/资源（只是粗略的球场估计就足够了）？
对此应用程序的任何其他想法和反馈将不胜感激。
谢谢！

Hello,

I am seeking assistance in selecting an appropriate FPGA for a fairly straightforward application.

I would like to use the FPGA as a simple pre-processor to a wireless RF module. The main purpose is to decimate oversampled data before transferring to the wireless module. Specifically, I need the FPGA to perform the following functions:

(1) Receive multichannel digital data – there are 16 data channels coming to the FPGA via SPI serial interface. Digital data is oversampled (10kHz sampling rate).  16 bits per sample.

(2) Decimate/downsample the multichannel data by a factor of 4 (probably using a CIC filter, or CIC + FIR compensation filter, or polyphase).

(3) Transfer the downsampled data to the wireless module via a parallel interface, or possibly via SPI.

(4) May need FIFO buffers at the input (prior to decimation) and/or at the output (after decimation, prior to transferring to wireless module).

Is there a recommendation for what Xilinx FPGA device would be a good fit for this application? Also, is there a recommended method for estimating gate count / resources required (just a rough ballpark estimate would be sufficient)?

Any other thoughts and feedback for this application would be greatly appreciated. Thank you!
