single-board computer

hi all

i am on my way building some sort of "box" which should contain a single-board computer. i know that my question is very naive, but:

-what is the "state-of-the-art" type of single board computer if taking into account that: -it should serve as a "platform" -deal with some almost real-time activities (streaming of a/d-data in the audio field) -run embedded Linux

i have found some examples of single-board "servers" on the web which seem promising to me. however it is very hard to find a price tag for that. and yes: price has some relevance to me...:-)

do you have any recommendations in this field?

thanks a lot!

michael

It would be most helpful if you could point to examples that are similar to the SBC that you have in mind, as well as some that you have already considered but have decided that, for whatever reason, they do not meet your needs.

hi rich

thank you for responding. i must admit that i am not too far in evaluation yet...

one promising boeard i found is this:

but i am not able if this board can "keep-up" against other boards.

best regards

I've worked with one of their smaller offerings in a couple of rugged products that have shipped. EMAC has a pretty good track record.

Ampro has been around since the Dark Ages, knows what they're doing, and has a solid reputation. FWIW, the first generation Ampro "Little Board" was a cutting-edge (for the time) 4 MHz Z80 running CP/M.

Care to share what you want the system to do? I have seen real time audio done on very low end processors since that was all they were doing. If you don't have any specifics on what the processor needs to do other than "deal with..." it will be hard to suggest anything.

I really don't see how you can know that you want to run Linux unless that is a customer requirement. Selecting an OS (or no OS) is normally a part of the design process after you know your requirements. Requiring an OS like Linux up front adds significantly to the requirements for processor speed and memory size. If your project really does not require an OS, you can likely get by with a much smaller CPU and lower cost.

If you can lose the Linux requirement, you can likely get by with a SBC with an Atmel SAM7 part. They use DMA to move data between the IO devices and memory. But then you may be looking for something along the lines of an embedded PC with rotating mass storage. I just noticed that you used the term "server".

BTW, what exactly does "platform" mean? I have been seeing this term tossed about for a number of years now and I don't understand it. I even see this in the FPGA world. Anyone care to enlighten me?
