Hi everyone, I am currently doing my Final Year Project. I have coded the algorithm used for Simulation. It is based on simple Subband Adaptive Filtering with 2 Bands. One of the Analysis Banks contains low pass filter as its coefficient and the other contains high Pass filter as its coefficient. (I will post up the diagram if it is helpful). This part is under process section Immediately aft...

Hi, I am working on accelerometer sensor based vibration analysis. For ?spectrum analysis I am using DSP processor. Now I need to scale my output( magnitude of FFT) according to my input signal. I am using low pass filter, Decimation, and windowing to process time domain data.? Because of these function there will be non-linearity in output.? Is there any standard method for co...

Hi I am using ADSP 21369 and using command line interface to build the project. I am getting the following link error(see below) when I tried using the UART example. It is due to the macro SRU2 defined in sru21369.h. [Error li1021] The following symbols referenced in processor 'p0' could not be resolved: 'A2_ [_A2_]' referenced from '..\..\lib\dsi.dlb[dsi.c.doj]' 'A_ [_A...

Hello everyone, I am Marko Kanadi from DSP research group of Institut Teknologi Bandung I am new to Blackfin (BF561EZ). I have a problem with 32x32 bit multiplication built-in function on Blackfin, which is the mult_fr1x32x32. Underwritten is my code : fract32 x[2]={0,0}; //mixtures fract32 test=0; x[0]=(fract32)(iChannel0LeftIn); //integer to fract32 conversion x[1]=(fra...

Hi, I'm Marko from DSP research group of Institut Teknologi Bandung Currently I'm tackling with the implementation of a statistical signal processing algorithm on Blackfin BF561EZ. I just started working with the machine thus, you can consider me as a newbie. In my work, the machine needs to handle calculations with real numbers. The problem is even the algorithm is successfully compiled, the m...

hi all i'm using adsp2181 ezkit lite board. As we all know 2181 has only 1 timer. my requirement is to use this timer for 2 purposes using status condition. i'm using timer for UART and i need to use the same timer for generating some control pulses for my project. my idea is to use a status check. i.e. if dm(status)=1 then the timer is dedicated to UART and if dm(status)=0 the timer is...

I'm doing tests with hardware "ADSP-21262 EZ-KIT LITE" and the software as "Block Based TalkThru (C)". I put in the function "BlockProcess" my algorithm. But I see that output from the algorithm introduced me take effect only on 2 / 3 of the output signal. I also annoying peak (spurious effect) between a block and another. Can not understand where is the anomaly. Can you help Maurizio ...
