Dear all,
I want to acquire data using DMA (large data) and store it to large memory acquire and allocated using malloc in c++
later I want to take the partial data and save in separate files. Please refer to the image for more clarification(although it is worst diagram but was short of time)...
Hi Jeolby,
Thank you for response.
I am using 3rd party DSP board (I dont want to mention name on an open forum).
Any ways. It has two an FPGA part and other ADC+PLL+clocking part.
So in the FPGA part, they have given virtex 6 for putting custom design by the user,
where as the virtex 5 acts...
TrickyDicky, pardon me,what do you mean by front-end simulation
The kit provider has provided with the PCIe communication softcore, hence I
do not have to develop that from scratch. Is there no possibility to use chipscope....
When I contacted the vendor he said to attend relevant material from...
Hi all
I am having trouble with my design where I have ADC input coming to FPGA and then processing thing are done...
Then output goes through PCIe to computer.
I cannot know how can I simulate ADC signals with the FPGA...
Moreover how can I do the in-system simulation for debugging. since I...
Hi all,
I have an unknown and irritating error in VHDL, I have declared my signals as std_logic, but I recieve the following error for my case strucure. (I have put both error and code snippet below)
Line 128: Type std_logic does not match with the integer literal
architecure behavahioral...
Hi all,
I have a program in c++ that communicate with the FPGA device, I tried its console version, it works fine.
Now the next target is to get every thing in GUI, I am taking data from ADC using FPGA,
some of the parameters are for example, drawing that data in the graph form (now I am...
wooow....
That was sarcastic...But good :)
well I never asked for help in terms of code etc. I just asked the way how to start, I think 1 week is more for me since I just have to show the basic communication now, rest is later (which is actually not even final yet, unless I do this)...
But any...
Dear all,
I am trying to start simple displaying project on monitor using DVI interface of ML605. I have to submit it to the supervisor in 1 weeks times. Although I am starting reading the manuals etc. but any other related material would be helpful.
Looking for response,
Jaffry

Ah very sorry, the issue is already resolved, I actually was checking in Oscilloscope with the AC coupling.
Thank you very much for assistance
Bests,
jaffry
Thank you it works.
Now I just put the code for blinking LED code as the clock generator, and then check the signal at the Oscillosope, but the signal worse, It is some worst distorted shape of the sine wave sort of something. It is good to glow the LED but not suitable for the Clock, what do...
so in my code I set only first and second configuration register, the other registers I did not set, should I check the data sheet for them or should I only change the top 2 registers(which when I checked were right).
Also I am using 20 Mhz clock with 22pF capacitors, but I dont know what is...
Dear all,
I am using PIC18f4550 while using winPIC programmer for downloading, the thing is that I want to generate the clock and although this is the simplest thing just toggle the port I cannot do that.
Also I tried to just glow the LED constantly, even then it is not glowing, instead it is...
TrickyDicky.
While implementing I face one more issue, it is regarding increasing bit size. I hope you can suggest something.
My original bit size of inputs is 12 bit/12bit for angle/position coordinates.
But after all additions and esp multiplication, it increases to 42 bit(that too a/c to my...
TrickyDricky!
Thank you for your quick reply.
Yes it is 12 bit number. The implementaion is just from 0 to PI/4 the integer bit is considered 0 in the algorithm.
Yes I know fixed point is fixed point, thank you for reminding, well this thing just slip from my mind and I confused it.
Yes you...
Dear all,
I am implementing a research paper for my VLSI course.
I have few questions in this regard. Please see the question in red
I have to multiply the data with the PI value, i.e. 3.1415... I am aware of the fixed point implementations and what I know we have to do normal operations...
