Hi All, I'm in my last year of Electronics Engineering, and am doing a project on VoIP using ARM. My group and I are currently looking for ARM boards, and have recently shifted focus from ARM9 to ARM7 for want of money. Can I port RT- or Embedded Linux on ARM7TDMI(the one architecture easily available in India)? What're the requirements? Awaiting answers, Thanks.

Hello, Could anybody explain some of the difficulties involved in creating a custom embedded linux board. I require one for a project I have in mind. Basically it needs to be a descent speed (~> 500MHz) and drive an 800x600 touchscreen panel. The PXA270 chip seems ideal. I have looked at various boards on the market but they all seem to do too much or too little. The gumstix verdex bo

Hello, I'm currently making the initial design decisions (and hence the most important ones) about a project, which will involve a processor running Linux. The project's initial definition is to take data from an MPEG video chipset and store the stream in a long file on a Disk-on- Key. So the concept is simple: Write a driver for whatever video hardware we're going to choose (still not ...

I'm designing a device that can display high resolution (at least 1080i or 1280x1024) images to a LCD monitor. I don't think that much 2D/3D acceleration is needed for this purpose. Lower hardware cost is the first priority, although ease of development is important too. What is the best route? 1. Microprocessor only, to run embedded Linux and software-based display controller 2. Micr...

With the industry scuttlebutt saying that Toshiba will likely kill HD- DVD very soon, I expect to see a lot of hardware dumped on eBay cheaply. The earlier players were basically an embedded Linux PC with a 2.5GHz Pentium 4, 1GB RAM, a 256Mb flash drive and various other bolted-on subsystems; is this still true? I haven't been able to find a community of people turning these idiot boxes i...

I need the processor in my design for simple switch-scanning LED-ligh...

I am trying hard to avoid embedded stuff these days, but potential contract has come my way recently that needs some embeeded stuff. So whilst I am nutting out requirements I also need to put thought to software. I have made the descision that the software must be based on an OS and must have a c++ compiler. RTOS is not required. So the debate in my brain has been fired off. My first thoug...
