Hello Everyone, I've run into some issues recently with importing a library of I/O cells provided for our technology, Global Foundaries GF 8RF-DM (previously 130nm IBM cmrf8sf). I am now creating a pad-ring for our completed core circuit but am running into many issues regarding LVS. I have communicated with the library provider (ARM) regardi
Hello Can anyone tell me and explain to me how can i use the FIFO memory to synchronize my FFT core with it? I need to control my FFT core completely and i have tried many ways but still no result, so i want to know how can make use of my FIFO to control the data streaming into my FFT core. If you can help me to solve this issue in my design i wo
Hi all. Hopefully someone here can help advise me on this issue. I have an iPod/music player called a Bowers & Wilkins 'Zeppelin air' that stopped working a while ago. Zero power to the unit despite fuses and external supply being good. The power supply board in the unit is known to be the fault with these devices. So I removed the board to s
And she comes in Monday morning and says "Oh - I got a streaming video player, I don't watch DVD's any more" :) :) :)
Potentially all operations that can't be implemented with microcontrollers due to lack of respective hardware interfaces.Pls be specific. There are applications requiring the ability of the circuit to perform almost real-time operations, such as dealing with video streaming, protocol conversio
these refer to start of packet and end of packet. they are part of the avalon streaming protocol (they dont have to be used)
Hi! First of all, I hope this is in the correct forum section. We have a problem that I hope someone could help us with. We have a unit streaming out a 16 bit number using 16 LVDS channels at a rate of 180 MHz. The connector is a 68 pin VHDIC. Together with the data a clock signal is sent. I would like to interface two of these to a computer
you can get the streaming pictures and store it. but the application should support the option for getting the frames. some link for setting wifilinux:
For voice it is adequate to have 4k to 8k samples per second. (I think I once heard 8k is a speed used for audio streaming over the internet.) Hence if you wish to store 10 seconds of sound, you'll need 40k to 80k bytes. 256 possible data values is satisfactory. This is convenient to have one byte per sample. 5-bit DAC playback... There is a cha
Hi, I'm going to work on a automotive project, here the requirement to automate the video streaming through CAPL script? is it possible to do that? It is too urgent requirement, can any one please help me.....
I have a DVR camera with a serial port and also an ethernet port. 4 cameras are connected to this DVR. I can connect this ethernet or serial port to my controller. From my controller board (running on ubuntu ) which also has GSM, would I be able to stream the video to a server ?
fs = 1760; % sampling rate You may hear musical tones at this low a sample rate. However sample rates for audio are normally much greater than this. I heard the figure 8kHz for video streaming. CD quality is 44.1 kHz.
Hi , I would like to design a WifiDirect Camera Hardware that streams and records video. I have the requirement as follows. 1) It should be compact size (half the size of palm) 2) It should have both Bluetooth and wifi direct. 3) It should have slot for micro ssd. 4) It should be a night vision camera with PAL or NTSC Can you guys help
I want to use FT2232H in fifo mode for streaming out data. The external altera FPGA reads the FT2232H at a fixed rate of 48kb/s. On my PC side, what I need to do is to continuously check the number of bytes in the transmit queue. If the bytes falls below 32, the program will feed 256 bytes using FT_write. But when I use FT_GetStatus(ftHandle,@RxByt

Hi all, for my thesis work i am planning to simulate video streaming in QUALNET. does anyone know how to simulate it.... please do help me with the simulation procedure. and also i need your suggestions also. Thank You
Hi edaboard readers, I'm a long time reader, but decided today to make an account to share what I'm doing. I'm currently knee-deep mired in a job search after graduating with my Masters degree in EE earlier in the year. In order to keep my skills current and have something to show for my time other than rejection emails, I decided to undertake w
Greets all! I figured that if what I want to do could be done, and where to look to research it, the best place to ask would be here. I searched all the tags I could think of but came up empty. Both here and via Google. I have audio files encoded as AAC that I recorded via SDR, streaming, or just plain audio capture of my favorite morning show
Certainly Multichannel streaming from your "headend" ISP is possible, but being a fee-based technology & service only your ISP knows for sure. In the meantime, there is XBMC software and XBMC HUB with addons for any computer, for recorded video, OTA (Over-the-air)with a digital tuner to router e.g. HomerunHD ASTC digital tuners from
SALAM TO ALL i am final year student of computer engineering and looking for final year project.. initially i have to interface a color camera with microcontroller which is mounted on robot to see the live streaming on my laptop ( i have some experience with ATMEGA32) :?: :oops:

"Digital Video and Television", by Prof Ioannis Pitas, 2013 The book provides the most up-to-date introduction to digital video and television. The entire process is covered, from video production, to its delivery through broadcasting or streaming. Digital video cameras, video acquisition, color theory and visual quality are presented. Various v
Assuming that the Mobile is connected to Wifi router and supports 3G/4G data communication scheme(s) as supported by the router,The microcontroller can upload the data,either by streaming it continuously or by sending it all in one go to the Wifi router through ethernet...and the router can send the data.Only thing..How would the user on the
1. You dont need to read all the pixels at once. With some line delays and shift registers you can easily slide the 3x3 filter over the streaming input to provide a streaming filtered output. 2. An array will synthesise to a bram - so they are the same thing, unless you access the array incorrectly and it infers a load of registers (and it will ma
Hi, all I'm going to develop an application of wireless audio. The diagram is as follows: 104545 Audio mother and several audio children are placed in a house, the distance between them is ranging from 2 to 10 meters, they may be isolated by walls. Audio mother is like a call center, and always ready to receive requ
In my view what you are looking for is very complex project ..... First of all you need to first think of capture of video from camera ......then converting it to proper streaming option based on the bandwidth .......and then think of transmitting it over GSM using certain protocol and ........then proper reception of it on the GSM connected device

Make a neural net with number of connections, such that memory storage for the neurons doesn't all fit in the fpga. That way you will have to make some streaming approach, which should make things extra interesting. Hey, you asked for ideas. :P Now go implement that and send me a link to the design paper when you're done! XD
So you define the result for the MAXIMUM word size you will have to handle. And then the smaller words you pad with zeros. Problem solved. And if you don't know the maximum word size either then that's too bad. :P Then you would have to change the design constraints such that you DO know the maximum, or adopt a streaming approach.
But the thing is that we don't know how to transfer the multimedia data over internet. Does anybody know about these? Please help us. You may try vlc streaming
Hello, I would like to start a new project, my idea is this: an acquisition system based on pic, maybe pic32 but not necessarily, sampling freq. 100kHz, 24 bit, streaming data to tcp/ip client. Number of channels: as much as possible compatible with bandwith. Few years ago I made a pic32 based board that performs a playback of a wav file from a S
Hello! I'm facing the problem of simulating an FFT core generator in vhdl. I have written a FSM and a test bench file to run the simulation of the Xilinx FFT core (streaming) in ISE. I'm using a DDS module (from the core generator also) that generates a sinusoid at the input of the fft. What I'm getting at the output is something weird.
Hi dear all, sorry if I perhaps ask an even too easy question for some of you: At a customer site, I had a SystemC TLM2 code snippet that was like: req.set_streaming_width(4); req.set_data_length(req.get_streaming_width()*burstSize); req.set_address(_slaveBase + ADDR_SPACE); req.set_read(); result
I am using FFT and IFFT in FFT Transform 5.0 core.I am getting correct result in Radix 2 burst mode, 128 transform size, natural order i/p and o/p width 13 bits and scaled. I am giving an array(128 samples taken from ADC from zero crossing) to FFT core and IFFT .But when I Taken samples random(128 samples and not from zero crossing) my o/p is not p
Dear all, I have designed 8-point FFT using Xilinx IP core. I have selected floating point I/P and O/P options with Pipelined streaming I/O. I have written a sample testbench for 8-point input and I got some o/p. In general The back to back connection of IFFT and FFT should give same results of I/P and O/P. 1. I have generated 8-poi
Do you need only full duplex speech quality audio stream (hands free) or do you require also A2DP which allows streaming of high quality stereo sound? Since you need to include the AM/FM radio I suspect that you are looking for the latter one. One module that includes A2DP and has buildin codec is
Hi all, I import a GDSII file in IBM 7RF technology and while streaming in I specified the LayerMap file (cmrf7sf.layermap) but while I try to do Calibre DRC it shows me the following error message: ibmPdkrunCalibre("DRC") Starting DRC on top cell in window:3...

I am trying to generate a clock signal, and send data to control the device, with PIC18F2550. The data starts early than the real clock signal (CLK), and there are two data (data1, data2) for each data stream circle. The time diagram of clk and data can be seen in the attachmentThe control device can accept up to 20MHz clock signal, but I am
The handshake signal rfd and rdy are intended to be used in conjunction with the clock, not as clocks itself. Doing so will mess up design timing. But you would probably still get some non "xxxx" output, the point should be corrected but doesn't necessarily cause the problem. I'm however not sure if you are using the streaming interface correctl
I don't know what type of FFT you need to have, but for streaming FFT, take a look at Radix-2^2 FFT. It was easier to implement than radix-4 FFT, but had the same performance as radix-4.
hi, i am working on a mcu circuit that can communicate another device, and it receives so many message lines. My mcu doesnt have enough ram to store all message lines. So, i tried the code below with my pic18f4550 and 48 mhz clock to filter the message lines and pick the required values from the streaming message. static char messag
hi all, i am designing a new hardware which can communicate an external device via rs232. My hardware should send some commands to the external device and receive some specific values. the problem is; that ext. device sends a lot of value and information that i dont need. i need to pick some values from the data message which is sent by ext.
Ok This is the problem with tools like this - it can be easy to think that because you have an HDL coder, then you should be able to put your code on an FPGA right? wrong. Basically, you need to re-engineer the algorithm so that its in a suitable format to go onto an FPGA. 1. It needs to be fixed point 2. It needs to be streaming, rather th
I'm totally new for almost all the network simulations, but I'm really in need of one right now. what I really need is,a network simulator which is very helpful for content distribution and to demonstrate video streaming. I tried to see some, like NS-2 but the problem is, it requires programming language which I have no experience on it. Could s
