IPC with Message Passing

I'm looking for suggestions on possible IPC mechanisms that I can implement in my self-made OS for an AVR32 board.

My current choice is implementing the massage passing mechanism described in the books written by Tanenbaum.

Is this a good choice? Are there easier way to implement IPC?

Thanks

Perhaps the ZeroMQ project can be an alternative for you?

My suggestion is to review the message passing primitives that QNX RTOS (www.qnx.com) supports before making any decisions. I spent several years programming a complex multi-process system in that environment, and it stands out as the best message-based O/S I have ever encountered.

Some specific points that spring to mind (it's been a while now):

  1. Message data copied between process memory space by the kernel so that a bug in one process cannot affect another.
  2. Ability to send and block for a reply.
  3. Ability to drop a message on a queue and move on immediately.
  4. Ability to send a message an block indefinitely until the receiver responds; the receiver may receive and process other messages in the meantime - this is way more valuable than you at first think it will be.
