Version Control Systems

Version Control Systems are systems for providing source control to hierarchical collections of source directories (repositories).

It is important to note that Version Control Systems are not a build system but rather a way to control disparate versions of code as it is developed over time.

CVS

Version control systems are also called a CVS

CVS is a short term for Concurrent Versions System, network-transparent program that allows developers to keep track of different development versions of source code.

CVS does not maintain multiple versions of source code files but keeps a single copy and records of all of the changes that are made. When a developer wants a particular development version of a file, CVS will reconstruct that version based on its records.

Popularity of CV Systems

CVS systems are widely used in both software and hardware development companies.

Now days it is hard to imagine company that develops hardware or software not to use some kind of Version Control System.


Algorithms and architectures for dedicated computer systems

- course prerequisites -

Main topics: Mapping Algorithm onto the Architecture Hardware synthesis Hardware description Special purpose data paths DSP applications

Outcomes (be familiar with): Hardware synthesis ASIC, ASIP, FPGA Simulation, testing and verification

Semester IX: 2+2+1


Course organization Lectures (2 classes per week)

Hardware synthesis Hardware description Special purpose data paths DSP applications

Oral exercises (2 classes per week) VHDL – Hardware Description Language

Syntax Description of special purpose data paths Description of DSP applications Description of control units and interfaces

Labs (1 class per week) Aldec Active-HDL and Xilinx development environment VHDL description, simulation, synthesis and implementation

Data paths Memory modules Controllers and interfaces


Students’ projects

Outcome of course is to teach students to do description, testing and verification, synthesis and implementation of dedicated architectures, data paths, controllers and interfaces in Aldec’s and Xilinx’s development environments.

Students’ knowledge is evaluated through projects. Typically average student spend a month or month and a half working in project.

Projects are devoted to special purpose data paths, dedicated coprocessors and DSP applications.

Concluding remarks

CVS as support makes communication between teaching staff and students much more easier and more frequent and brings better results.

Using CVS as course support students are prepared to be a part of a team!

They found it as interesting and useful experience
