S83

Program of graduation level

This was a work to implement a virtual machine with specific machine instructions and an assembler compiler for this virtual machine. The language is also specific for the type of instructions of the virtual machine. The compiler was implemented in the program "Montador.pas" and the virtual machine was implemented in the file source "S83.pas".

The programs created using the S83 assembler language can be executed in the virtual machine.

After the execution it is possible to see the state of the memory.

Figure: Impression of the memory state.

The program "Montador.pas" is used to compile assembler S83 programs.

The assembler program in then converted for binary code.

The compiled program store the information of which memory address it will be stored when executed.
