Re: RTOS in FPGA

Hi Tusu,

 

That depends on what you consider real time. xilkernel seems to be a preemptive OS, but I do not know how deterministic it is. Another free OS is FreeRTOS (www.freertos.org), which has a port for microblaze. It is licensed using a modified GPL license, meaning you can probably use it without having to disclose your source code.

 

Regards,

 

Sytse.

Re: RTOS in FPGA

Hi,

 

Here is a good article on RTOS that has the formal definition and some examples.

 

RTOS-es can be classified as soft real-time and hard-real time. An example of free soft real-time OS that can run on Spartan FPGAs is embedded Linux. For example Petalinux  distribution running on a MicroBlaze processor.

 

I'd speculate that xilkernel is a hard real-time OS (unless this claim is disproved by somebody more knowledgable).

 

 

Thanks,

Evgeni
