Hi, I am running an efficient FFT algorithm on DSK 6713 where twiddle, and some variables are generating again and again in the main and taking so much time which in result affecting the real time processing. How can I save them as .const to avoid their calculation every time ? Thanks for your help. BAS

Hi, I have one question which may sound stupid but I am really worried. I have implemented 'Efficient FFT Computation of Real Input' on C6713 DSK. In the code I have defined one FFT function fron TI DSP Library in the following way: void DSPF_sp_fftSPxSP (int, float *, float *, float *, unsigned char *, int, int, int); I am not gettting any error or warning on compiling the proj...

Hello Everyone, I am trying to do a Peripheral Device Transfer ( a PDT write by programming the EDMA and EMIFA registers ) from a FIFO on a Virtex-5 FPGA to a DSK6416 SDRAM. My question is, when I look at the EMIF out clock ( ECLKOUT) on the scope it DOES NOT look like a square wave but rather like a sinusoidal wave with a frequency of 125 MHz and amplitude is 1.6 V. Isn't ECLKOUT su...

I got EVM6437 with CCS3.3.38.2 and BIOS5.31 I need processing video from one camera and give it in output DAC. I found "Accessing_Pixels_In_A_Frame_1_03" based in "video_preview" doing that, but I can't debug. I recompile "video_preview" and there's no troubles, I load it and it runs (CCS tells me "running"), but I can't "go to main", stopping in breakpoints (SW/HW). I see video camera ...
