Hello I am trying to compute DFT using FFT in BF535. My need is to compute DFT of about 1 megasamples(1 million points). But since I'm very new to the field and am using a DSP for the first time, I do not know whether this is possible. If it is possible using BF535, how much time does it take to do it? Thank you.

Hi, Super ADSP stars and Gals and Guys and ..., I got a problem with my BF535 EZ-KIT. It does not talk with my VDSP 3.1 properly. Wat I had done is: I load some codes using session of ADSP BF535 EZ-Kit Lite. The codes using SPI polling method. And since I halt it in the middle

Hello, I'm porting a voice codec to Blackfin DSP (BF535). Until recently I didn't have the Blackfin evaluation board (ADDS- BF535-EZLITE). So I used Visual DSP++ 3.1 for Blackfin to simulate the DSP and evaluate the codec performance. The cycle count that I obtaine

Hello I am trying to run the 'Talkthrough C.dpj' example program of the BF535 EZLite eval board. Unfortunatly it does not run because it does remain to stay in the while loop at line 141 within the initialisation.c (function Init_Codec) //wait for frame valid flag

Hi All, I would highly appreciate if any one can answer my query. I have written a small program in C to check the cycle consumption for different operations in Blackfin (BF535) I am using the demo version of Visual DSP++ 3.5 simulator for this purpose. The code which I have written is as follows... void main(void) { long int a,b,i1,i2,i3,i5,i6; a=4; b=2; i1 = a+b; i2 = a*...

Hello, We had a similar problem, and a colleague of mine found out that there is a statement to be put in comments (in short, removed) if you are using a higher version of the BF535 chip in your ez-kit. Check lines 103-104 in the Init_Interrupts function: // for chip revisions > = 1.0 remove the following instruction (needed for anomaly "IMASK bit polarity") *pSIC_IMASK = 0xffffffcf; So, si

Dear All, I am working in interfacing BlackFin processor onto the PCI bus. Can I interface BF533 with a commercial PCI controller like PCI9030. Do I need to add any logic in between blackfin and PCI9030(or any other copmmercial. BF535 has an inbuilt PCI controller in it, but the the analog.com website says the chip is not in production. Can anyone help me out? Regards

Hi, I'm currently experimenting with the BF535EZKit and the example USB code provided by AD. My problem is that I cannot seem to compile the PC example code which communicates random data to and from the BF. It appears as though some .h files are missing. Am I missing something silly? Does anyone have experience getting
