I worked on the core network system for GPRS (2.5G wireless system) before. We used a similar environment, not the same type of card, but the binary is also compiled and loaded on to card.

I don't really like your idea of directly sharing data among processes, this way of multi-processing has been proved wrong from a structural point of view, and largely reduce the maintainability of your application.

For that GPRS system I worked on, we used both TCP and UDP to communicate between processes, it has been proved that performance was not a problem with TCP and UDP. Also we used stream at any tightly-coupled point (have to check whether your card support any thing similar to Unix stream.)

(I think you made some typo, by saying multi-thread across multi-processors, any way).

As for language, c is usually the best choice for this kind of project.

Writing perl script and then compile into c might shorten the development cycle, but will definitely hurt performance. I would assume anything that runs on card, requires high performance and throughput.

Also I would imagine that all the libraries, if any, you can find are in c.

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
