Can Debian do multi-core "MY WAY"?

[Richard Owlett <rowlett@cloud85.net>]

I date from era when when "memory banks" were switched via 
contents of a I/O port ;/
Anyone remember era when 8085 was "state of the art" ;/

I envision
  core A using memory range X
  core B using memory range Z

My individual tasks could be handled by a 2MHz Z80

Can Debian do it on GHz machine?
