Realtime OperatingSystem for Analog Devices DSP 21020

Hello,
 I'm searching for a OpenSource Operating System for ADSP 21020,
 The I've no dma, no video, no audio.... nothing to require more
driver.
 I need just Semaphore, Event Management, Irq Management.
Thanks

I didn't know ADI still manufacture this chip!

The current DSP software development suite from ADI (VisualDSP++)
comes with an integrated OS, but I don't think it supports the 21020.

How are the input signals connected to the DSP? How many signals are
there? How many DSPs are on your hardware?

If you tell us more details then perhaps we can help you. I'm a fan of
space applications :-).
