#IPC Heterogeneous Multi-core FFT Test**Table of Contents** [TOCM] [TOC] ##1. ARM side (1) Apply for CMEM space and divide it into two pool spaces, one for storing the original time domain data and the other for storing the processed frequency domain data. (2) Convert the starting address of the CMEM space to a physical address. (3) Initialize the time domain data. Here, set a superimposed sine waveform of 50Hz, 100Hz, 200Hz, and 500Hz. ```c float *dataIn = (float*)msg->dataIn; for(j = 0; j < PAYLOADSIZE; j++) { dataIn[j] = sin (2 * 3.1415 * 50 * j / (double) PAYLOADSIZE)+sin (2 * 3.1415 * 100 * j / (double) PAYLOADSIZE)+sin (2 * 3.1415 * 200 * j / (double) PAYLOADSIZE)+sin (2 * 3.1415 * 500 * j / (double) PAYLOADSIZE); } ``` (4) Send a message to the DSP, which carries the starting address of the CMEM space. (5) Block and wait for the DSP to process the data using FFT, then return a message to the ARM. (6) Save the processed data to a file. The file is named as follows: <ignore_js_op> <img style="cursor:pointer;" id="aimg_533421" aid="533421" src="/bbs/static/image/common/none.gif" onclick="zoom(this, this.getAttribute('zoomfile'), 0, 0, '0')" zoomfile="//bbs.eeworld.com.cn/data/attachment/forum/202104/15/173452dggjlx7h2ij77lyq.png" file="//bbs.eeworld.com.cn/data/attachment/forum/202104/15/173452dggjlx7h2ij77lyq.png" inpost="1" onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})" /> <div class="tip tip_4 aimg_tip" id="aimg_533421_menu" style="position: absolute; display: none" disautofocus="true"> <div class="xs0"> <p><strong>1.png</strong> <em class="xg1">(54.23 KB, downloads: 0)</em></p> <p> <a href="javascript:;" class="loginf" >download attach</a> <a href="javascript:;" onclick="showWindow(this.id, this.getAttribute('url'), 'get', 0);" id="savephoto_533421" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=533421&handlekey=savephoto_533421">save to album</a> </p> <p class="xg1 y">2021-4-15 17:34 上传</p> </div> <div class="tip_horn"></div> </div> </ignore_js_op> ##2. DSP side (1) Block and wait for the ARM side to send a message to the DSP side. (2) According to the DSP side virtual address mapping table, convert the physical address of the CMEM space into a virtual address accessible to the DSP side. (3) Call the function to perform FFT processing on the data. ##3.

It's all very well, the test run seems to be going smoothly

Jacktang posted on 2021-4-15 21:25 Very well done, the test run seems to be going smoothly

Now I am getting the hang of it and I have obtained the results of the fft operation, but the output does not seem to be correct when simulated with MATLAB.
