|
|
* @todo Generate VCD or GHW files directly so that GTKWave can view
|
|
* the resulting trace. See
|
|
* <http://www.ic.unicamp.br/~ducatte/mc542/Docs/gtkwave.pdf>
|
|
* @todo The compiler section could be replace by an embedded Forth interpreter
|
|
* The one available at <https://github.com/howerj/embed> would work well, the
|
|
* metacompiler could be retargeted for the H2 processor instead of its own
|
|
* 16-bit virtual machine. This should cut down on program size and increase
|
|
* functionality.
|
|
* @todo Allow state to be saved/loaded by serializing the objects within
|
|
* here. This would allow the simulation state to be saved and resumed.

/* This is a fairly fast trace/CSV generation routine which avoids the use of fprintf,

* speeding up this routine would greatly improve the speed of the interpreter when

|
|
* also greatly speeds things up. It can be used in a roundabout way to generate

* a file viewable by GTKWave, its output can be fed into 'csv2vcd' after some
|
|
* minimal processing with AWK, turning it into a VCD file, which is viewable in

/* This Forth virtual machine is based on the H2 processor, but it is meant
|
|
* to run on a hosted system. It is a small, limited virtual machine, but
|
|
* capable of running a cross-compiler (metacompiler) and saving the resulting
|
|
* binary. This will eventually replace the assembler/compiler. This requires
|
|
* another file which contains the metacompiler, and an image for the virtual
|
|
* machine.
