It seems a bit unlikely to me that there's really a single indivisble
bit of hardware with 23 kilobytes worth of register area. Is there
a better way of structuring this so that there are a number of
sub-memory-regions that cover this space each with their own
read/write functions (and perhaps with their own state structs)?
(eg instantiate five CPUs at the right locations.)
Dear Peter,
Sorry, but I don't quite understand what do you mean. Which 23 kilobytes
you have in mind?
And what benefits we get from division whole region into some
sub-regions? Current approach seems quite simple and clear. Isn't it?
