Hi! I have a custom board having ADV7171 ,ADV7183 and BF532 Processor.By using it i want to display a Frame on the monitor. ADV7171 is in NTSC mode at the reset.so, i have easily displayed the NTSC Frame on PC monitor(i have a TV tuner which has s-video input and VGA output. By using it i have displayed the frame on PC monitor). But, when iam displaying the PAL frame , i can't able to get...

Hai everybody, ---> I am using Sharc-21160M processor in multi processor environment. ---> I am doing inter processor communication through link ports. ---> interruptf function is been used to map my function to the ISR. My problem is I am getting into ISR(in Tx side) once I transmit the data from one processor to the other. But the processor is hanging, since the control is not

Hi! we are trying test the booting process in our Custom board.we want to boot the processor(BF532) from SPI Boot(BMODE 11). we are observing CS(Chip select) of SPI memory is going 1 to 0 transition when we are resetting the board.But, booting is not started. Then we have tried with the emulator.... This is what we have done First we have put hardware Breakpoints at locations 0xEF000000(B...

Hi, Anyone can direct me how can I program the codes to have the UART working so that i can communicate with the PC using the hyperterminal. Or is there a reference or example code for the 533 UART so that i can study and from there code it. Thanks. Regards, Get your new Email address!

Compact Flash Interface Using BF548 ATAPI

Has anyone out there successfully interfaced a CF card (configured in True IDE Mode) with an Analog Devices' Blackfin BF548 processor via its ATAPI interface? Page 24-2 (p.318) in the "ATAPI Interface" chapter of the "ADSP-BF54x Blackfin Processor Hardware Reference" manual states: "Interface to compact flash (CF) configured in True-IDE mode". (This, to me, implies that this interface shou...

I am working on EEG data compression.When Reconstructing the eeg signal using wavelet coeficient i am using psnr(peak signal to noise ratio) to calculate the reconstruction error. Is there any other metric which can be used(like PDR).? -- Thanks and Regards Simeranjit Singh Brar

Hi, I am trying to see if we can port OpenCV on BF561? If anyone has done this, please could you help me figure out how exactly this can be done. Also, one thing I have noticed is that somehow, we have to convert the floating point arithmatic into fixed point so as to have efficient use of the BF561 processor. Has anyone been able to do this? Any help and pointers would be really app...
Esoteric (apparently) FFT question

Hello. I hope a general question is okay here. I've read that it's possible to use a half-size FFT if you interleave the input between the real and imaginary vectors, but in all my research, the output processing required has remained a bit sketchy. You'd think this would be better publicized given that it sounds like such a useful technique. My best take is that one needs to do...
