Reconfigurable FPGA

Hi, i was going through FPGA's then i came across reconfigurable technology's in computing with the help of FPGA's. well how and why this reconfigurable method is useful in optimizing the designs?", where as an ASIC overtakes in many aspects such as in speed,etc. I got a paper to write based on the reconfigurable technology on FPGAs. I've googled few topics which states reconfigurable technology is the future. But unable to start the paper giving it a valid reason.

How to make an ASIC from a FPGA? Answered

I am starting to play around with FPGAs, and I want to eventually make my designs into a permanent IC. Is there any company that will od that for me? All that I've heard of are companies that take designs to mass produce them, and cost hundreds of thousands of dollars. But I only want one or two ICs, and I want to pay a price that makes sense with the design (simple designs cost only a little, then the price goes up as complexity increases). Is there anyone that does that?

What's an FPGA? Whats an CPLD?

What's an FPGA?  Like what's it compared to a microcontroller?  Please no links to google or wikipedia :P  I mean, from what I've read, it just seems like theyre inferior to a microcontroller, so I don't get why people use them.

Would this be appropriate for an FPGA/CPLD newbie? Answered

I've had experience with electronics in general and the Arduino, but I've never done anything with FPGAs or CPLDs. Would the CoolRunner-II CPLD Starter Board be a good start? Am I correct in believing that it doesn't require any sort of serial-to-USB converter or separate programmer to be able to use it? Basically, will I need anything other than the board? (Not including the USB A to mini B cable) Thanks, dedgerton EDIT: Oops, it might be helpful if I give a link to the board: here it is.

How to give analog input from 3.5 mm jack to FPGA (Spartan 3e)?

I am working on a voice transmission project by using Spartan 3e. My code works just fine. My problem is that i give analogue input to adc side by using a potentiometer and see the changes (as digital) on leds ( digital output is assigned to leds). Here is the problem, i cut a headphone into two and connected 3.5mm jack side to my phone to play music. There are 3 cable which are golden, blue and red. Golden one is connected to "GND" pin , Red one goes to "Va" pin (at adc input). i didnt touch the blue one. When i play music, i see no change on leds despite the fact that i did see by using potentiometer. What am i missing ? Do i have to setup an external circuit before giving the analog signal to Va input ? Thanks in advance.

LCD Screen as external monitor using FPGA?

Hello everybody, So I have a bunch of dead old laptops laying around which I want put to good use. The LCD-screens (among other parts of the laptops) works perfectly. I want to make an external monitor using one of these LCD-screens which obviously is possible by using a controller board. But is it possible to use an FPGA instead and actually connect it to my Windows computer? I have read this article: Can anybody help with this?

How to build a Gamecube Portable using the LCD screen and case from iBook G4 Apple Laptop? Answered

I would like to use an iBook G4 17" for the majority of the housing and screen for the portable. Heard I need an FPGA converter board to switch from VGA on the gamecube side to LVDS on the laptop side. I would like advice on how to best do that and also what kind of power supply I could use to run this system internally. External would be ok but internal even better! I have a gamecube and the iBook G4 already.

Genetic Circuit Design

Hackaday recently posted an article about genetic programming which was pretty cool (although technically it used a stochastic hill climbing algorithm....but who's counting?)The really cool thing was posted by acedio in the comments: genetic circuit designWhat these researchers have done is implemented genetic circuit design on an FPGA to create a circuit to light a light when someone says "go" into a microphone and turn it off when someone says "stop". Which is not really groundbreaking...but the way the genetic algorithm created the circuit is pretty amazing, it used what normal designers would consider unwanted characteristics of the circuit such as stray capacitance and inductance between components to "create" unavailable components out of logic gates, and because of this the researchers have no idea how it works!Computers can now design circuits in ways that would be damned near impossible for humans to do, how cool is that??!Deep thought here we come!

want to display my text on a tft lcd

I have make a project, it receives a sms from the sending side (on sending side there is any mobile) on receiving side there is sony Ericsson t290 which receives the sms. mobile is connected to the serial cable (rs-232) and the sms through at commands is brought to the micro controller after passing through max 232 which converts rs232 logic to ttl logic for micro controller  after that my sms is display on the led dot matrix display which is controlled by shift register and Darlington pair. Now i want some help in it.. i want to display this sms on a tft lcd monitor or on a lcd tv.. now to display on a tft monitor i either need a vga access and some circuit which can display to that standard or can use fpga ( spartan 3) and to display on the lcd tv i either need to build a video stream of the lcd should use some thing else to display on it.. plz i need some help to solve this problem i need to display my sms recived on either of lcd of tft

16x16 LED panel direct control

Hi all, I got 10 LED panels of 16x16 LEDs each. Now I want to create a big modular display system with these and I'm also planning to post this on the instrucatbles website once I succeed. But I have some problems getting started. I spent alot of time reading all LED matrix related topics on the website here but none of the designs matches the fixed design I have on those panels. Instead of using some sort of multiplexing, 32 shift registers are used for 256 LEDs which means every LED has it's own shift register output. Put then again, I also find 3 buffer ICs on the panels and I have no idea where they are used for... Below the info I have now: 1 PANEL: - 16x16 yellow LEDs - 32x M74HC4094B1 8-bit shift registers - 3x 74HC125N Quad buffer/line register, 3 state Pictures: First I want to work with only 1 panel and be able to control this by putting images on it. But for this I have to understand completely how the hardware is built up so I first want to create the schematic of 1 panel. Can somebody help me with this and get me started on the project? First goal: just control 1 panel with an AVR to put some text on it and let is scroll. Final goal: be able to connect multiple panels and configure the software accordingly to the panels used. Then use a PC to put images on the screen and maybe even create a live feed (webcam capture). For this maybe an FPGA should be used to have more processing power/memory. Many thanks already in advance!

convert any CRT TV or monitor into a vector (XY) monitor?

NOTE: I since found a couple links that might shed some light on the question... From HackIt: New uses for old CRT monitors It would be very hard to do, but it is possible a CRT could be converted to a vector monitor. Perfect for playing Asteroids, perhaps under MAME. You would have to replace all the control circuits, probably with an FPGA and three ADCs (x/y/intensity). Posted at 8:58 am on Feb 25th, 2008 by MoJo Television and PC monitor experiments old cga/vga monitor to oscilloscope ? The inquiry: Maybe I am over-simplifying but I was reading one of those examples of hacking into a CRT's horizontal & vertical yoke controls to sync to music: and had the idea that it should be possible to create a DIY XY monitor (vector display like on an oscilloscope, Vectrex, Asteroids, etc.) for an Arduino or other uC, MAME or Vectrex emulator, from any TV or CRT, once you have hacked into the electron gun's yokes. My understanding being: Raster display: the horizontal yoke (an electromagnet) sweeps the electron gun from left to right turning on the beam wherever there's a "pixel" at that line (which lights up the phosphor at that point making it visible), then it starts over at the next line (vertical yoke moves down) and draws the next line, and so on, Vector display: instead of rendering a moving image frame-by-frame using top to bottom/left to right scanning, shapes are drawn directly to the screen by positioning the horizontal & vertical yokes at the starting point, the beam turns on, and the yokes repoint to the end point, thus "drawing" the line inbetween the 2 points (I would assume this is for straight lines, not sure if circles or arcs are possible?) then the beam turns off, and the yokes get re-positioned to the next line's starting point. I'm not sure what turns the beam on & off or what kind of timing might be involved, obviously that needs to be controlled somehow. Or for color, where instead of a single white (or green, amber, etc) phosphor exists per pixel, there are multiple (red, green, blue) per pixel, and the beam hits each one at varying strengths (or for a varying length of time?) to 'mix" the primaries to the desired color? I'm not sure how that gets handled in a color vector monitor, but I would assume it's something similar to raster? So if we can hack into a CRT's X/Y yokes and move them around with an audio signal, can we control the yokes more deliberately from a microcontroller to plot specific shapes or text, hence a vector display? For those audio/TV hacks, what is the audio signal doing to the yokes that causes them to move? Whatever it is - voltage, resistance, etc - this is what our device would have to control. Possible proof of concept version: make a device to control the yokes' position etch-a-sketch style with a couple of potentiometers, and turn on the beam with a switch or button. If you see a dot of light moving across the screen then it works. I am thinking the controller might need to be "calibrated" for the individual CRT? (Maybe build some kind of calibration mode into the device.) You might dedicate a microcontroller to driving the display - it could receive text or vector shape coordinates via serial, store the shapes to draw in its own memory, and persist or refresh the image independently, freeing up processing power for whatever device it's displaying for. Another idea would be maybe add some kind of way to read light pen's coordinates, thus making the CRT an input device that can be read from the microcontroller or PC (the Vectrex had a light pen right?)  [This would be a cool mod for the Arduino composite TVout as well.] So is this idea possible without a ridiculous amount of work & parts?  I may be dead wrong about how this stuff works (I'm sure that if this was possible, someone would have done it by now?) but figured it can't hurt** to put the idea out there. I have visions of 4-player vector Arduino pong, Asteroids, Tempest, PDP-1 Spacewar!, vector NES Duck Hunt, a vector etch-a-sketch or lightpen drawing or animation program, or vector Atari Video Music. Possibly an open source color vector games system. Or just a vector display system for any Arduino or microcontroller project, made from any TV. **WARNING: maybe it CAN hurt... Evidently hacking into any CRT can be deadly, you have to discharge the CRT and capacitors properly or you can get killed. So please be careful. This definitely is NOT for kids to try at home.
