Hi guys, Need suggestions of realistic applications that can fit in 10k LE fpga, compression? networking? video? Pls feel free to drop any suggestion. Thanks!
Hi, I am interested in an IP core for 2D wavelet compression and decompression. If someone has something that can be synthetized in an fpga it would be great. Can you u/l it in the 20-day section. Super thanks! TurboPC
It is verification only to design MPEG2 decoder to use fpga. Verify function to use fpga and actuality chip need method that embody using ASIC.
it's me again. i'd posted this in the other topics already but i found out that this topic here is relevant as well. I hope to find a complete vhdl code for data compression or any file compression. then it can be decompress to get back the original file. i'd been looking for this code but to no avail. hopefully it will be using the huffma
I hope to find a complete vhdl code for data compression or any file compression. then it can be decompress to get back the original file. i'd been looking for this code but to no avail. hopefully it will be using the huffman to compress, but any compression method is always welcome. i'm currenly using the max plus II v10.2 with 10k (...)

hii , i m working on hardware implementation of some data compression technique, have to write a verilog code n then synthesize it on an fpga. can any one tell me which is the best compression technique for hardware. i mean faster n less power consuming. thanx
Hello everyone... Im planning to implement an image compression algo on the spartan 3 starter kit for that i'll need to store the image somewhere. Storing it on the fpga (implementing a RAM on the fpga ) consumes a lot of area. So one option would be to store the image on the SRAM provided on the starter kit. But then how do i (...)
I have never really worked on compression. However, I would like to comment on your second question. I don't think that a microprocessor (let alone a softcore MP implemented on top of CLBs) would be adequate for such a heavy and real-time dataprocessing task. You will have to design the processing mechanism in hardware (fpga). Also, I would reco
i want compress a block of data about 900k, i want to efficient algorithms of compression that are easy fit on fpga. what are the compression algorithm's that can be implement on fpga? it is better if verilog source is available :D Added after 1 minutes: any one have previous experien
Hi everybody! I ask to you in the name of Video Group (Computatinal Math. Dept., Moscow State University). We are working in the area of video processing (most of our algorithgms are available for free in a form of filters for VirtualDub, you can find them here ). We plan to implement some of our algorithms in hard
This doesn't directly answer your questions, but . . . A general-purpose CPU implemented in fpga logic (such as NIOS and MicroBlaze) has very poor performance compared to a dedicated silicon CPU (such as a Pentium). Even a modern Pentium is stressed trying to do video processing. For high performance, consider building video parallel processi
Hallo, everybody! I'm new at this forum and I've been searching for some useful info about implementing a DWT (Haar) and SPIHT compression on fpga. I've found some questions, but no answers by now :( I've read about SPIHT quite a lot, made a MATLAB code... Now I've started to plan VHDL programming, but I don't have much experience so I coul

Hello everyone.. I am doing project on video i want to keep frame data in external RAM and then i want to interface external RAM with Block please suggest me how to do so.... plzz reply urgently.... Thanks in advance Ashish
The experience shows that the fpga board is connected to PC through the COM port very well. The UART IP core is needed only. It may be free. The only disadvantage is the speed. Ethernet, USB are speedy, but they are much difficult and time consumable to install. Only when you have the proper license to the interface IP core, and the company w
do ur algorithm works on fpga board
Any one can help me ... I am doing my final year project " Image compression using DCT implementing in fpga" If any one having the code in VHDL or Verilog please sedn to me. Arthi
Hi, I would like to buy an evaluation board. Im interested (so far) in implementing some audio/video processing algorithms. In the future it could be some projects connected with wireless communication. I am considering two boards from Digilent: - Virtex-5 OpenSPARC Evaluation

Hi All, I am working on Huffman Encoder/Decoder for text compression/Decompression.And here are the things not clear for me. 1.How can I give text input (Whole text once) to the fpga. 2.When I encode the data the output code length is not fixed and how can I manage this with constant I/O pins of the fpga. 3.When (...)
RAM requirement will depend on number of frames to be stores, its dimension and so on... Because fpga fabric has very limited RAM, particularly Spartan 3E, you must consider storing frames on external flash ROM.
can IDCT be computed on fpga in the same architecture used for computing DCT? changing the bit precision of the stages This is for an image compression project.....
hi, I'm doing an image compression project,i had used matlab to convert the image into a hex i need to load them into fpga .The hex file is as follows(only 8 rows are shown below...) 9f93969795919294 9f93969795919294 a09793939796938e 9e95918e97959193 9e9b958e95939292 9e9d938f9090938f 979a9691938d9192 9e9b958e95939292 .......
Due to the high cost of typical fpga development board, I'm thinking about buying the fpga die and build myself the needed board to program it with all the I/O. What should I need to do this beside the soldering station, copper, acid and a good PCB software ? Thank you very much
Have you followed all the coding guidlines? You can write code that will simulate correctly, but if you have not followed any coding guidlines for synthesis you have no chance of getting it on an fpga. Without seeing your code I have no idea if it will work. To get it on an fpga you need whichever vendors compiler tools (ISE for Xilinx, Quartus fo
i am doing my final year project related to video compression using fpga, for that matter i need to send an image first through matlab, get it compressed and see the results, what I am getting back from fpga can be seen thorough .dat file. if anyone can suggest me any solution?
I am working with a custom board that will be used for evaluating the performance of two measurement ADCs (AD9649 & ADS6143) at high temp. The output of the ADCs is connected to a Cyclone 3 fpga. An SPI interface is used to gather data from the fpga and log it into a computer. What I currently have is the following: 1. A 2^14 length FIFO buffer

thanks you aji_vlsi i really need that software as i'm designing a compression engine using VHDL but i think its better to run the project in C language for a single i really need the software as its urgent.thanks for the information.
This may be a dumb question, but why do people use the Omnivision sensors that are very hard to come by while you can get others sensors from Digikey or others much easier? Please post some DigiKey (or other vendor) part numbers for the image sensors, and we'll provide some comparative criticism. On a diffe
thanks really helping me... actually I am not good in layout design. Can I just focus on HDL and finish by proved it using fpga? can anybody give an idea?
To send the data throug a serial port is the slighest problem. Wavelet transform is not a problem too - you can look at the proper Matlab toolbox. The problems are: - buffering large array of the image in fpga - slicing and traversing pixels of the transformed image - algebraic coding - resulting file forming. The another problem is there
