I'm not aware of dedicated mux devices for RS232 or RS485 interface. Of course you can use any existing mux device according to your specification. I guess, that't it less expensive and more realiable anyway to use individual driver devices for each interface and perform the mux action at (...)
we are doing our final year project on "watermarking scheme for copyright of digital images". it is based on DCT and NLFSR .please u have any ideas about this project & how to write coding in matlab help us.
I'm designing an ECG machine, and I wish to multiplex the lead inputs in the very beginning (or maybe just after 1 amplifier stage) in order to save resources. I wanted to know if there's any 8 in 1 mux available which I can use to multiplex such low power signals?? I was looking into sn74hc151, but hav very less idea, so as what parameter valu

Hi, I am designing a DAS system which needs a board level precision of 14 bits. So, I have decided that it is better to go with 16bit precision in component level. Input signal frequency : 200Hz (max) Archtecture : Differential I need some suggestions from the experience. for argument we consider an analog mux from Analog Devices, ADG12
I'm trying to sample from 8 channels using my dspic33fj128gp802 chip. I've had four channels working fine up until now, but trying to use the alternative mux switch isn't going to plan. I've tried to change the settings so that the DMA interrupt is polled after each second sample/conversion, in a hope that I can fill an eight word DMA buffer fo
Hello guys! How are you? Well, I´m working with RFID from Texas Instruments. I am starting a new project that I want use 2 antennas for the same electronic. Can I use a mux between antenna and electronic? What are the parameters that I need look for make a best choice about mux? Tnx very much! PS: My RFID (...)
Hi, Scan chain will not be helpful in testing memory. Basic aim is to check manufacturing defects in memory. In BIST we write some data into memory and read back the same address. So we make sure that read write operations are happening properly. As already suggested, you can design your own bist controller and wrapper logic for memories. Please
Sorry for your time.... Why i can't see images on this resource? My Browser is: Opera. Thank you.

Hi, I am a new member of this site. I start with a simple question - How we can implement a 5:1 mux using any number of 4:1 mux?What about unused ports?
hello freinds i am using two commands two open tmax csh , source /home/student1/synopsys/synopsys.cshrc , tmaxgui ........ after that tool is opening . I have done dc(dft compiler flow ) to my design and generated corresponding design.ddc, .spf(stil file) for the Rtl design in dc. I h
When the CE input is 0, the output of the mux is Q, so that the FF will hold its present state on every clock, i.e., no change even though the clock is still running. When CE=1, the ouput of the mux is D, and the Q output will follow D on every clock edge.
I have a problem with mux, can somebody kindly help me? Let's take 2 to 1 mux for example: In RTL code, you may write: wire a1, a2; wire out; wire sel; assign out = (sel == 1'b0)? a1 : a2; The question is: If sel is constant 1'b0 and a1 is also stable. But a2 may change cycle by cycle. for the real (...)
hello friends!, In my application I have to select any 1 of 3 devices at the startup using user input. These 3 devices pin-outs will be connected to FPGA. I have to select only one of user choice. The pins are "clk, din, dout" pins for interface.3 devices are same....Now I have written a code to interface with this device. But my choice is to work
Hello all, I have written an application that converts a GIF file into an .LLB Orcad Layout library file. I have published a shareware version fully functional for images not exceeding 100x100 pixels, which is enough for small logos. for larger images, there is a registered version for (...)
read data mux is controlled by the decoder to decide which one control the bus!
hi all, Any one have idea regarding "C Programming for Playing Vedio or displaying image " how to set which port itis reading and which port it is going to be write . if my displaying device is connected to RGB what i have to do . what is the procedure for general purpose processor (PC) and also for particular ARM+DSPprocessor
Dear all, I am doing my master's in signal processing. I am currently doing research in audio and image processing. I have been processing over huge spectrogram images. I am facing the problem of noise reduction. Currently, we have been using Wiener Filter technique, convolution stuffs and the use of Band pass filter for noise reduction.
Hi, Can anybody tell me how to implement 5:1 mux for Serialiser ? Please, post any referred paper for it. Thank You
Hi Given multiple mux choices(2:1, 4:1, 8:1,10:1 muxes), how do you design a 40:1 clock mux for low power? There is no limit to the the number of the standard muxes you can choose. Thanks
Hi, I am new to multi clock designs and facing some problems in clock domain crossing . I have gone through the 2-3 FF synchronizer for single bit CDC and have also gone through Async FIFO . But there is not enough information on Dmux synchronizer which is widely used for multibit CDC. It would be of great help (...)
too define an array do like this define variable_name then you have a class by possition in the three dimentional array you can also define arrays using c stuctures like x=1000 y=1000 z=1000 variable_name variable_name variable_name int p=3 p= (x+y+z) + (-x-y-z) p is then
Hi to all, I know the basis of system acquisition, An OA -> ADC -> UC -> Display. But now i am in charge to desing a system with 16 analog input, with a 1KSample/channel, and i read that this kind of system need a window filter before the mux to eliminate the aliasing and another after it to eliminate the noise introducted by it. And i couldn´t
Dear Reader Which device is better for analog channel switching?. I have used multiplexer(mux) for analog signal (the signal is weak... 10mV under) channel switching. Recently I hear, analog switch is better than mux. But I have no experience about analog switch. So if you have good idea about difference between (...)
system gates is equivalent of the logic utilized interms of 2 input NAND gates. There will equivalent for each of the components used in the logic(flip flops, ram , mux....).
first one will synthesised to priority encoder and second code to mux... for timing you better stick to the second coding style.
Salam, SOP = Sum Of product. You can implement any logic circuit by draw it's truth table then from the truth table you can find equation for the o/p using AND & OR gates only. CPLD uses these tech. It uses programmable AND & OR Gates array. Note: this in simple, but actually it the Logic Cell contain Flip-Flops and mux for handle (...)
Hint: make a mux for do1 and do2. assign do1 = (d1 == 3'b000) ? 3'b101 : (d1 == 3'b001) ? 3'b101: ...
Hi all, I 'm designing ethernet mac IP CORE, which supports 1000M/100M/10M/TBI mode. There are many clocks in my design. In deifferent mode, different clock is used, so I use several mux for clock selection. But I 'm not confident with my systhesis&STA script about clock mux. Anyone can help me? or paste your synthesis (...)

i think using a case statement is better way to code a mux for eg reg data_out ; always @ * begin case(output_select) 3'h1: begin data_out = {2'b0, saved_rx_data} ; end 3'h2: begin data_out = {1'b0, saved_rx_data} ; end default: begin data_out = 8'b0 ; end
1)how can i guarentee that my FSM output is glitch free.......... Register the FSM outputs 3)what is the size of LUT if i want to implement two nindependent logic functions of 5 variables.......... 4 input LUT with a Fx mux for 5 variable logic but we cannot use the same slice for another 5 variable
Anybody has done the project onthe topic "Fingerprinting protocol for images based on additive homomorphic property.
RTL : Functionality of device written in language like Verilog, VHDL. Its called RTL if it can be synthesized that is it can be converted to gate level description. Netlist: You get a netlist after you synthesize a RTL. This is gate level description of the device. The high level statements in RTL will be converted to gate level. for example IF
design the circuits for the outputs that you want i.e. astable, monostable etc etc.... then multiplex these outputs using a analog mux for every 5 seconds using a counter... for turning on the circuit after 5 second use input from voltage across a capacitor which is being charged using a current source...
Thanks .........I need muxes.I got in that site.
Ternary operators can be synthesized if they are used along with the assign statement. When used with the assign statement (conditional assignment), this code yields a mux, for ex, assign y = (a==b)? 1'b1:1'b0;
hi frnds... i know that clock recovery is done at RX end from incoming data itself. but how a clock can be embedded into tx data at TX end?? any circuit, any info.. regarding that.... plz help....
I want to use binary segmantation for images with k-means and C-fuzzy algorithms using matlab. i have already wrote the algorithms and they work well. How can i convert the grayscale image into binary using the clustering data? Can you help me.
Is there a way to capture a playing movie (like printScreen is used for images). for example, you're playing an arbitrary video or an animation (say flash, etc) and you want to capture it so as to be able to replay it. Is there a utility or software that can do this? Thanks in advance for you attention :D

Hello Friends, I am trying to simulate Quad ridged waveguide in HFSS. Please Find attached file. I found this example in One paper, where I got dimension & I implemented to see how it works. But in the paper there are results which Plots graphs of S12 for TE10 mode & TE20L mode.(check attached file for images) I don't know how to excite (...)
You can use a mux for the selection circuit.
you can create a 2 digit BCD counter by using two 4 bit counters and some logic gates.The main idea is that when the count in the first(LSB) counter reaches the value "1001"( 9 in decimal) it is reset to zero and the second(MSB) counter is incremented by '1'. I am not sure about why you need a 4:1 mux for this. --vipin vhdlguru.blogspo
Hi All, I'm trying to find the movement between two different image for images' registration. In order to speed-up things, I'm trying to find the maximum of the cross-correlation of the two images. I'm using OpenCV - the cvDFT() to generate the two Fourier transforms and than, using the cvMulSpectrums() to obtaining the (...)
