+%DONE
+
+Back in the beginning of 2012 a leading automotive company requested the Czech Technical University
+to develop a Engine Control Unit (ECU) for automotive applications. Real-Time Systems group at the
+Department of Control Engineering from the Faculty of Electrical Engineering developed a hardware and
+Software platform to the needs of this industry. The hardware uses Texas Instruments TMS570LS3137 CPU
+and has was built with automotive standards and interfaces in mind. It uses a real-time operating
+system and was directly programmed in C.
+
+Nevertheless, in accordance to company policies the Software developed for the engine control unit must be
+designed in a safe and auditable way. The company has the policy to implement the Software for their
+system using Model-Based Design:
+
+ Model-Based Design (MBD) is a mathematical and visual method of addressing
+ problems associated with designing complex control, signal processing and
+ communication systems. It is used in many motion control, industrial equipment,
+ aerospace, and automotive applications. Model-based design is a methodology
+ applied in designing embedded software.
+
+In order to meet this requirement an interaction layer between the platform and the Software the company
+uses, Matlab/Simulink, must be implemented. This document describes the implementation of this interaction
+system.

+
+%DONE
+
+Main objectives of this project are:
+
++ Allow C code generation from Matlab/Simulink models for custom made hardware platform.
++ Implement model blocks for some of the peripheral units of the board for use in Simulink programming.
+
+
+At the time of this writing the objectives of this project are considered successfully achieved.
+
+== Benefits ==[benefits]
+
+%DONE
+
+Expected benefits of this project are:
+
++ Enabling faster implementation and rapid-prototyping of Software components through the use of model-based
+ programming.
++ Enabling better and clearer visualization of Software implementations for the hardware board through models.
++ Improve auditability of Software system for automotive applications.
+
+
+At the time of this writing the benefits of this project are considered enabled.
+
+== Final outcome ==[final_outcome]
+
+The main products generated for this project are:
+
+- Simulink RPP Target.
+- RPP Library and API.
+- Simulink RPP Block Library.
+- Simulink Demo Library.
+Each of this product is described deeply in the following sections.

+= Project setup =[project_setup]
+
+This sections describes the Software and Hardware setup for development. It also describes the layout of the project
+repository.
+
+== Development environment ==[development_environment]
+
+This section describes the Software setup for development.
=== Operating system ===[operating_system]
+This project was developed on a GNU/Linux operating system. For development it is recommended to use a Debian based
+operating system for development as most of the tools are easily available from repositories. Relevant OS information
+is:
+
+- Ubuntu 12.04.2 LTS AMD64.
+- Kernel 3.2.0-48-generic.
+- GCC version 4.6.3.
+
+
+No test for cross-platform interoperability was performed on the code developed. Although care was taken to try to
+provide platform independent code and tools this are the elements that are know to be Linux dependent:
+
+- LCM1 hardware control tool. @@
+ This tool is both GUI and command line capable, the following just affects the GUI part.
+ Command line should be usable under Windows systems. @@
+ __Cause__: Serial port search algorithm is Linux dependent and Gtk 3.0 dynamic Python bindings aren't available on
+ Windows operating systems.
+- TI CGT support file for RPP Simulink Target ````target_tools.mk``". @@
+ __Cause__: Use UNIX path separator ``/``.
+- Simulink RPP Target download script ````rpp_download.m``". @@
+ __Cause__: Use UNIX path separator ``/``.
+- Simulink RPP Target install script ````rpp_setup.m``". @@
+ __Cause__: Use UNIX path separator ``/``.
+- Simulink RPP Block Library block compilation script ````compile_blocks.m``". @@
+ __Cause__: Call Matlab MEX executable with Unix name.
+- All CCS projects under ``<repo>/rpp/lib/apps/``. @@
+ __Cause__: Paths are configure using UNIX path separator ``/``.
+
=== Version Control System ===[version_control_system]
+The version control system used for this project is **git**. The repository of this project
+contains all the files produced during development, including documentation, references, code and
+graphics. Also the GUI application **gitk** was used to easily review changes. To install both
+execute on a terminal:
+{{{ bash
+sudo apt-get install git gitk
+}}}
=== TI Code Composer Studio ===[ti_code_composer_studio]
-
+Code Composer Studio (CCS) is the official integrated development environment for developing applications
+for Texas Instruments embedded processors. CCS is multiplatform Software based on Eclipse Open Source IDE.
=== Matlab/Simulink ===[matlabsimulink]
