Hello, I m working with Matlab on image compression. Now I want to put my code into a TMS320C6x DSP, I think I m going to write my functions in C. The problem is : I ve got images from a camera (5 images / second), they go into the "IEEE1394" cable and must come into my DSP. Is there a starter kit which includes IEEE1394 "link" ? Tx.

Hello All, I am new to DSP programming and am experiencing some difficulties implementing filters on a fixed point DSP (TMS320C6416). To keep it simple, I started trying to implement a single pole low pass filter with a corner frequency of 500 Hz while sampling at 96kHz. I have obtained the quantized filter coefficients using Matlab's fdatool. I have then written down type 1 direct fo...

Hello DSP experts ! =A0 Actually, I am working in a project, implementing the MODEM using DSP6713, = and I hope I can gain your deftness in this case. After implementing the whole algorithm on DSK boards (using MATLAb simulink= + Code composer) I encountered a problem. It seems all parts of model include 32 QAM, Timing recovery, Equalizer and = carries recovery algorithms act well during s...

Hi, I try to find fft of impulse sequnce. But my fft output is not correct when i compare with matlab. Actually, fft of impulse should be one in all frequeny. My bug code given below #include #define N 4 void main(){ short Twiddle[2*N] = { 0,32767,...}; short InputFft[2*N] = { 0x4000,0,0,0,0,0,0,0}; short OutputFft[2*N]; short I;

I am a novice using the PADK board based on 6727, I want to implement a FIR filter to get the Hilbert Transform of the input signal, the coefficients are obtained by MATLAB. The C codes in the CCS is as follows, but the output wave have discontinuity points every several cycles seen from the oscilloscope(the picture cannot be attached). The DAC buffer is set as int dmaxDacBuffer[PINGPONG][STEREO]...

Hi all I'm trying to implement a Root Raised Cosine filter (Fsample = 3.84 kHz) with a DSK6455 for a WCDMA transmitter and i'm not quite sure where to start. I've simulated a filter in Matlab which automatically upsamples the data [-1,1], but i'm not sure how to implement the upsampling & filtering in C/C++. Is there any documentation available on the C/C++ implementation of RRC filters ...

I am using the PADK board based on C6727 dsp chip and want to implement SSB modulation from a monotone input signal. There's a way (from IEEE magazine)to generate the analytic signal composed of the in-phase signal and the quadrature signal using a pair of FIR filter coeffecients A and B (B is the reverse version of A). In the matlab simulation, when the input singal is of mono frequency, the outp...

Hi all, I'm trying to implement the RLS alogrithm for noise cancellation in C with the TMS320C6711DSK but dont know how to initialize and set parameters like the P matrix using C. All the examples i have seen implement it in MATLAB. I have already implemented the LMS algorithm using C but the more complex RLS is posing a problem. Any help would be greatly appreciated. Thanks.

Hi all I want to receive 70 MHz PM+BPSK modulated signal. Video bandwidth:138 kHz Modulation index for PM: 1.2 radian Subcarrier frequency of BPSK:65536 Hz. I have been using Matlab /Simulink and TMS320C6713 DSK. 1. I need suitable ADC daughtercard for C6713 DSK. 2. What is the sampling rate according to this spec.s? How can I calculate? I want to proof my calculation method. ...

I get the correct FFT output "shape" of a say sine wave using DSP_fft16x16t with C6415, but the it is in Q15. How can I accurately scale it back to a float value? Do I just have to find the correct value by referring to say the output of Matlab or other software? -Jeffrey

Hi I am trying to design some IIR filters using MATLAB and am facing an issue with group delay. Requirement: An audio data at 48KHz sample rate passes through two stages simultaneously, one through two stage decimation and one through high pass filter (cut-off 3KHz) in order to do different processing for lower and higher frequency content. Currently I am designing those IIR fil...
