[comp.sys.amiga] Multitasking: Amiga vs. Unix

dillon@CORY.BERKELEY.EDU (Matt Dillon) (08/23/87)

>#3. Two tasks competing for time.

#4.  One big difference is the lack of an MMU and process protection on the
    Amiga.  Sortof the way Xerox-Parc machines work.  The disadvantages are
    obvious.  The advantages are:

	(a) Context switch (read: system call) time is nil.
	(b) All messaging, signalling, and anything having to do with
		interprocess communication is incredibly fast and simple,
		making a multitasking kernel extremely workable.
	(c) Process switch overhead is nil
