    FPGA Operating system

    What are the difficulties of producing an operating system for a FPGA? Because from the few I have heard there is nothing made about that, or it can be as a PhD program..

    ... the whole question makes no sense as posed, as an OS runs on a processor, not on a programmable fabric.

    Re: FPGA Operating system

    Linux runs just fine on an FPGA, if the processor is programmed with a CPU.

    You talk about OpenSparc?

    Re: FPGA Operating system

    It seems that you lack a basic understanding of what an FPGA actually is...
    It's like asking what are the difficulties in an operating system for NAND and NOR gates...

    After watching these:

    You'll immediately see how little sense your question has.

    No
    More like NIOS, MicroBlaze, PicoBlaze

    Hello,

    Linux can run also on soft-processor like Xilinx Microblze or Altera NIOSII.

    Te question is too general in my humble opinion.

    Regards

    Re: FPGA Operating system

    There are hybrid parts with CPU+FPGA as well such as the Zinq and its counterparts from Altera.

    Hello,

    PicoBlaze has not enough resources to run OS - especially program ROM (form 1K to 4K words - Picoblaze instruction is 18 bit long) and RAM. Second issue with Picoblaze is lack of working properly C compiler (praktically one can use only Picoblaze assembler) - in contex of runnig OS on it.

    Regards

    Hello,

    why "No" as far as I know someone can run "Solaris OS" on "OpenSparc" soft-processor.

    See project site:
