Dear All, I am trying to implement the latest video compression algorithm H.265/HEVC. My idea is to implement the encoder first on Simulink and then Implement the Critical Block of Motion Estimation on FPGA. Can anyone suggest something regarding this project? Also, if you could please share some documents that could be used as a (...)
Hi.. can any one send me the VLSI architecture for implementaion of REED SOLOMON encoder and DECODER(using Reformulated Inversionless BM algorithm) with the step by step explanation how coding and decoding is done..VHDL code also.. thank u... daniel..
Hi Friends, I need to implement LDPC encoder and decoder on FPGA for below specification . Can any suggest a suitable algorithm please. 1. Throughput: A. Up to 8Mbps for low end devices like Spartan6 B. Up to 37Mbps for high end devices like Virtex6 2. Code Rate: a. 1/4 to 9/10 (at least in 6 steps) B. Programmable on block (...)
hi I'm working on IEEE802.16 physical layer and I need to implement a Reed-Solomon codec in verilog ,I have implemented the encoder successfully but the problem is decoder,till now I have completed the implementation of syndrome calculator but I have problem in Massey-Berlekam algorithm implementation , and also its concept (...)

I need your help. I need viterbi algorithm in c++ with realize algorithm of Trellis code decoding . if somebody have or found this algorithm i will be happy . I am from poland and I dont know good english . I need code with realize viterbi decoding for this encoder please help ..;
Hi all.... I am developing my own video compression algorithm in openCV. In the starting level I hv incorporated most of the blocks used in MPEG-2 algorithm (only algorithm not header formats etc.,). I hv completed both encoder and decoder side and verified in the same PC. I like to (...)
Hi all . Can any one upload Reed solomon Code(matlab code with explantion) for encoder and decoder. thanks in advance chin
You can put output from encoder to interrupt pin and detect state change. So you can meassure time between pulses to get rpm and use PID algorithm for motor speed control. You can also put timer on overflow on 1/10s and count number of pulses in that time period to calculate RPM. In this manner you will (...)
Conv. encoder and Viterbi Decoder in Matlab
I am doing a project about image compression in which I decided to build an encoder and a decoder using Matlab. The encode algorithm is: Read image -> 8x8 2D-DCT -> Optimal Quantization -> Huffman coding However, I have no idea about how to construct the optimal quantization. I know jpeg use a standard quantization (...)
I wanted to know that CABAC encoder of JPEG2000 and H.264 standard compression algorithm are similar or not.....(for still image).... I mean by knowing H.264 CABAC architecture can we design JPEG2000 CABAC architecture by some small modification.........
Convolutional codes are widely used to encode digital data before transmission through noisy or error-prone channels. During encoding, k input bits are mapped to n output bits to give a rate k/n coded bitstream. The encoder consists of a shift register of kL stages, where L is described as the constraint length of the code. a convolutional cod
I need matlab file that simulate turbo encoder/decoder using modulation and coding rate
Hi, h.264 standard specifies test streams (and results) that can be used to test your implementataion. You don't mention whether you want to do an encoder or decoder and what level/profile. In any event, chances that a h.264 implementation will fit into a cycle fpga are quite slim.
Below documents are for atmel avr controllers, but i suppose source code for cipher is separate from implementation specific . Take it from there . Both encoder and decoder are described DES bootloader AN from atmel AES bo
Hello all, I am studying MPEG2's Rate Control algorithm (its TM5 implementation). I found rate control algorithm is the most not intuitive part of all the encoder. I only need I and P frame. and I want to delete all the thing related to B frame. Shall I read some papers? and can you (...)
hai....I have a question about rotary encoder. I not really understand about the function of three terminal A,B and Z of encoder. From reading, I found that terminal A and B is used to determine the rotation of the shaft either in CW or CCW. What is the function of A terminal. From my (...)
Lame is VERY popular.. Especially with linux users.. That is where I heard about it from. I have never heard of the other encoder/decoder.. But I believe you will be a lot more support for lame as it is widely used
Well WMA algo is very vast and it is not available freely.I have also searched for the encoder algorithm. and for implentaion u need good documentation and it is very difficult to get it. thank you
