\begin_layout Section
EDE Overview
\end_layout

\begin_layout Standard
EDE is a software implementation of the ELB816 micro-processor along with
 a basic tool chain to develop and debug code for it.
 The block diagram below depicts the system that this project aims to implement.

\begin_layout Section
EDE Use Cases
\end_layout

\begin_layout Standard
EDE is highly modular.
 Each of it's components, with the exception of the UI, is written as a
 stand alone programs and works independently.
 Because of this design strategy EDE can be used in a number of different
 ways.
 This section details the use cases experimented with so far.
\end_layout

\begin_layout Subsection
Assemble/Upload/Execute/Debug
\end_layout

\begin_layout Standard
Using the tool chain in this manner is analogous to programming and run-time
 debugging a real-world micro-controller.
 Source code is assembled and written into the emulator's memory.
 The user can then use the debug prompt to step through program and probe
 the emulator internals.

\begin_layout Subsection
Interpreter Mode
\end_layout

\begin_layout Standard
Source code does not have to be pre-assembled.
 Since the command-line interface, the assembler and the debugger are all
 written in python, the assembler's functions can be imported into the interface
 code.
 This has been done to create a mode where the user enters assembly code
 at a prompt, and then that code is immediately assembled and executed on
 an instance of the emulator.
