#2 Design console interface and model calculation procedures

[Alexander A. Strelets]

Application must involve two parts:

• interface engine
• emulator engine

Interface engine must implement step-by-step console mode. All input is parsed and directed to the emulator engine; no service/auxiliary commands are introduced, but only commands directly corresponding to the user input on the emulated device. One step corresponds to one entered user command. The same approach is for the output.

Emulator engine must also implement step-by-step mode of operation. It shall provide a function for promoting the emulator state for one step and passing the entered user command; no other service/auxiliary functions are introduced. The current emulator state must be stored in static memory allowing external access for reading; it shall be accessible to the interface engine output feature.
