hi I am trying to write a vhdl code from its matlab code.its related to image processing and i have some codes like imresize that they are nearly 900 line codes. Is there any library for these basic codes in vhdl from previous works??? thanks
I did my research in Model Order Reduction for electronic circuits in IISc, Bangalore, India. I know C, C++, matlab programming very well, and vhdl basics+some more. B.Tech EEE. Not so much asking for jobs, as I want to know : should I even try in this market in India for an EDA job now?
Hi, I'm Electronic Engineer with 5 years of experience at the fields of DSP, FPGA and board design. Contact me if you need any help with your project, including matlab simulations, vhdl/Verilog codding and simulation, designing and modeling of communication systems, image processing. Shlomy.
I used libsvm for SVM classification in matlab, now after getting my result, i want use it for implement hardware, that i want use vhdl code in xilinx. All i know, i should use Support vector and some parameters that get them after classification, and used them in ROM for xilinx. But i know it just theoretical (...)
yes ofc its possible. Fir filter needs only DFF , adder and multiplier. In FPGA transponded fir architecture is widely used. Basically u can design wanted fir in matlab, export coefficient from it, change it to fixed values , and you can start vhdl implementation
sir,for what purpose we combine xilinx(vhdl/veilog) with matlab for particular image processing project. this is for speed or accuracy ?
This sounds like a setup issue. I wont be modifying the code for you as I really dont know matlab (or how easily it translates to HDL). But I do know you need to set the timing of the model to discrete stepped rather than variable. Also note that only a subset of matlab code is translatable to HDL. You're supposed to use simulink for HDL transla
Hi marinet, Here the issue is that matlab to HDL conversion is not easy ( mainly for synthesis ). The division in your algorithm is a major problem. Division algorithms are in fact not straightforward to implement in digital design. Basically you will not get division result in one clock cycle, and hence the problem. Thats why everyone insi
I should design a digital filter of first order ADC Sigma-Delta converter with 8 bits, an over sampling ratio of 64 (OSR = 64),and sampling frequency of 10.24MHz.I make it with matlab SIMULINK as shown in this
To start with, use Xilinx IP for FFT first and then you may try to create one yourself. Also as Tricky said, you should use matlab design side by side for design.
Hi, I am doing vhdl project using nexys2 board. I need to read the sensor readings using matlab through serial communication. My Code: nexys = serial('COM1', 'BaudRate', 9600, 'Parity', 'odd', 'Terminator', '', 'Timeout', 1); fopen(nexys); s = 's'; fwrite(nexys,s,'uchar'); scan_s1 = fread(nexys,1,'uint16'); t
Hi all,, i am jumadil, newbie at this forum... i have a problem with HDL coder.. i want to make a FIR filter with FDA tool (simulink matlab), and then i generate vhdl's code with HDL coder, but unfortunately that program didn't work.. how i supossed to do? is there any setting to configure the hardware's target? thanks for (...)

Hello, I am triying to simulate fir low pass filter in vhdl test bench, I get square waves from matlab as txt document, and I use ip cores for filter which I produced in matlab in fdatool. I am using text-io in the testbech. I have two questions 1-Square wave is 100Hz but in txt there are only -1s and (...)
Hello All Do u have a link where I can download a HLS tool? I need a tool that takes a C or matlab file and transfers it to vhdl. I already tried the HDL in Simulink of matlab but it doesn't support many of functions so I need another tool, any suggestions?
This is not really a vhdl problem, more of an algorithm problem. You probably need to model the system in something like matlab and see what kind of error you can cope with.

Hello all I want to implement a matrix-vector multiplication on FPGA. I have written a vhdl model for this purpose. Since I need to test it with large matrix,I should use matlab to generate a matrix file and use this matrix file in test bench module for testing my FPGA module. I need help for: 1.What must be the extension of the matrix (...)
Hi Dear all How can I calculate the maximum element of a NxN matrix? I know how to find it by matlab or C or even by using "for..loop" and "if" statements in vhdl but I am not sure that, Does this kind of coding synthesisable or not? ( I mean I didn't design a circuit for it before start to write the code). So what is your suggestion? Do I (...)
thanks for your answering TrickyDicky. I compiled my counter.vhdl code by Quartus Altera . then I exported it to counter.vhdl Testbench, (counter.vht).then I started matlab and change the directory into the counter.vhdl testbench directory and I entered "vsim('socketsimulink', 4449)" (...)

i need help that i have created a .bin file in matlab and i want to read it it vhdl...!! kindly help me out !! thanks alot !!
What do you exactly mean with "all the" matlab files? Mathworks has tools like the Simulink HDL Coder, there are also vendor tools like Altera DSP Builder. If they can convert a DSP solution without manual rework depends much on the initial design and your requirements for the FPGA inplementation, I think.

Hello every body I am doing a project on FPGA based acoustic noise cancellation systems. I did matlab and vhdl coding for this.Now I want to implement it on FPGA spartan3 board I would be very much grateful to you if you can provide me guideline for this thanks
If you've never done any vhdl coding (and I suspect, any digital design before), this is quite a hard one to start with. But you will need sin and cos look-up tables generated in something like matlab. Your whole design should be fixed point (not floating). Why do you need to convert to std_logic_vector? why not keep it all (...)
Hi all, Well I have to design a base index generator. When I say base index it is nothing but indexing the output of a binary counter. Well let me explain it clearly. We have a 13-bit binary counter who outputs are quoting to 4096 locations on a RAM and we have 13 such stages which is like the counter should count to 4K for 13 stages. Now we
You can use the filter toolbox of matlab (make a search for this in matlab help) and after that you can take the coefficients created and put them in vhdl.
Look at my attachment... Here I want to transmit my voice over UWB and to receive at receiver end. For that, there will be one ADC to convert my voice to input binary data(not shown above). Opposite action takes place at the receiver to play my voice on speaker. Blue blocks should implemented on single FPGA IC using vhdl. White blocks form R

You should start in matlab.
Hi all I'm a beginner to FPGAs and vhdl. I have a project in which the FPGA is to be used as an arbitrary waveform generator. The FGPA I'm using is the Xilinx Spartan 3A DSP 1800 board. The idea I have for implementing this is to generate the required waveform from another program, e.g. matlab, and send the generated (...)
