NIOS II: Choosing Opsys and TCP-IP Stack

Hi, everyone

We are just about to start a new project whic includes:

- Stratix

- Nios II

- Application with some real-time response (a kind of modem)

We have the choise between:

1. Linux + Linux-based TCP/IP stack (free)

2. MicroC + lwip (shipped with dev.kit)

Linux sounds good but isn't exactly a RTOS ?

The last choise has much lower footprint ?

What choise would YOU make ?

    Hi and Thanks for your meaning.

    The only reason I have for using an op.sys is to save development time! Meaning that we can use an available TCP/IP stack which I suppose is shipped with the OS.

    However, this may not be the case, as a stand-alone lwip implementation do exist?

    Hi Julveste,

    We are currently working on Linux benchmarking now. It will be ready in a week or two.

    The Linux 2.6 kernel now includes the low latency patch, and the preemptible patch is a selectable item. Unless you need "hard" real time performance, Linux will likely meet your needs. If you can wait for the benchmarking results, it may help you in your decision making process.

    Best regards,

    Robert
