This change lays the groundwork for adding support for Rev 3 3B2 models,
which includes the Model 500, Model 600, and Model 1000.
Rather than use the fixed strings "400" and "1000" in file names, the
strings "rev2" and "rev3" will be used, which allows greater flexibility
to implement various system configurations more easily.
Additionally, this change adds a copy of the Debug Monitor (DEMON) ROM
image for the Rev 2 board, to be used soon in a later checkin.
Refactor in preparation for the addition of a Rev 3 simulator for the
3B2/1000 system.
This change also includes a full cleanup of the rat's-nest of includes
and externs that plagued the 3B2 simulator and made it difficult to
understand and maintain. Headers are now required in the following
order:
compilation unit -> "3b2_defs.h" -> {... dependencies ...}
Finally, HELP has been added to the CPU device.
This change adds support for the WE32106 Math Acceleration Unit (MAU).
The WE32106 is an IEEE-754 1985 compatible floating point math
acceleration unit that was an optional component on the 3B2/310 and
3B2/400.
The MAU is implemented using software floating point routines. As
always, there may be bugs, but the MAU currently passes extensive
floating point tests with exactly the same results as a real 3B2/400
equipped with a physical MAU, so I hope these are few.
- All projects use identical include directories, library definitions and
library directories.
- Remove attempts to add XP support to projects that were converted to
.vcxproj for post VC2008 versions of Visual Studio.
- Require that git be available when building within a git repository
working directory.
