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.

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: http://g3nius.org/lcd-controller/ Can anybody help with this?

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: http://www.myalbum.com/Album=64MKOUJR 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!

Electrical / Electronics Engineering Position in Chicago - RAW THRILLS

Hi everyone, We have one of the ultimate electronics positions available. We make coin-op arcade games and constantly innovate our electronics to differentiate our games from the home consoles. We're looking for someone that can hack innovative technology and make it work in our market. Official job posting is below. Please check out www.rawthrills.com for more information about our company! JOB INQUIRIES SHOULD BE SENT TO jobs@rawthrills.com. Please include a resume and an explanation of your qualifications and interest. ====================================== Available Position: Highly Motivated, Entry Level Electrical or Computer Engineer Raw Thrills, Inc. - February 2010 Raw Thrills, the leading US manufacturer of coin-operated video games, is looking for an enthusiastic Electrical or Computer engineer to join our Electronics Engineering design team. You will be working as an efficient member of a small team on products that continue to gain domestic and international market-share. Immediately, you will contribute to the design and verification of electronics, firmware, and software. In addition to the internal team, you will work with partner engineering companies to develop & maintain products, and interact with contract manufacturers to troubleshoot issues on-the-fly as they arise on the production line. You will collaborate with several experienced engineers and programmers, all the while working independently most of the work day. At Raw Thrills, our arcade games are designed entirely in-house, from the ground up. They are composed of custom mechanical parts (wood cabinet, plastics, metals, etc.), an off-the-shelf PC, a monitor, custom wiring, custom electronics & interface devices, and custom game software. As part of the Electronics Engineering team, you will be involved in much of the arcade game’s design, from low-level circuitry to high level software, and everything in between: * ESD testing & EM compliance * Custom circuit & firmware design * System integration & validation (peripherals ↔ PC ↔ API ↔ software) * Operating System (Windows Embedded) maintenance * Device driver & device-application interface (API) programming * Device functional & longevity test design (including GUI PC software, firmware, and mechanical construction) * Coordination between mechanical and electronics design * and more! Required Skills: * Demonstrable working knowledge of C/C++: need examples of work and debugging proficiency * Solid understanding of digital circuit design & troubleshooting digital systems (from circuit to PC software) * Experience designing & implementing a digital system from the ground up (school project, internship, etc.) * FPGA (VHDL or Verilog) and/or MCU (c or asm) programming competency * Self-sufficient and motivated to independently learn * Proficient with standard bench tools: soldering iron, oscilloscope, DMM, etc. Bonus Skills: * Programming experience with PC↔device communication: USB, RS232, LPT, etc. * Schematic capture and PCB layout experience * GUI programming experience (Win32 or Linux) * Active knowledge of Linux / home Linux user * Working knowledge of common scripting languages (Python, bash, Windows batch, etc.) Example Projects: * Design low-cost circuitry to robustly control addressable LEDs for eye-popping lighting effects * Design, implement, and perform game system latency testing (create hardware/software as needed) o EX: What is the round trip time from button-press to in-game feedback?
