RE: [colorforth] multitasking

["Howerd Oakford" <howerd.oakford@xxxxxxxxxxxx>]

Hi Mark,

The display task spends most of its time polling the display refresh flag -
it only redraws the display when there is a chance that the image will be
transferred to the video memory.
Since display and keyboard are asynchronous, separate tasks is a good
solution.

I would like to add at least two more tasks to handle serial and ethernet
comms, as these are asynchronous too. I would not use a generic task
creation word - it is much simpler to compile as many tasks as you need when
you re-build the system. But this must wait until all of cf is ported to cf
and it can build itself...

Regards

Howerd

Is the second task in colorForth really needed? It seems the display can
clean up after itself, perhaps if you wanted to break the rendering into
chunks a 'pause' might be useful, the same effect could achieved by a
state variable however.
