Goals
The goal of this tutorial is to show how SocLib can be used to build a simple platform running the traditional "hello world!" embedded application.
Video 1: Description of the objectives of the demo
This video shows the objectives of the demo.
Video: Overview
Video 2: Description of the platform
The demo platform uses
- A Mips32 processor and its cache, running the embedded software
- A Ram component, containing the code and live variables
- A TTY controller, displaying messages
- A VCI/OCP interconnect, connecting the above components altogether
In this video, the basics of the VCI protocol are also presented.
Video: Platform
Video 3: Running the simulator
This video shows how to start the tutorial0 simulator, and displays the expected result "Hello world!".
Video: Simulation run
Video 4: Building the platform
This video explains how to describe a platform from scratch, and the role of each component. In particular, it describes the important notions of encapsulated Instruction Set Simulator (ISS), segments and mapping table.
Video: Building the platform
Video 5: The mapping table
SocLib is used to describe NUMA shared-memory platforms, and this video explains the logic of address mapping and decoding. All the information needed to design a mapping table is described here.
Video: Mapping table
Video 6: VCI link template
This video describes the various template parameters of a VCI link.
Video: VCI link template
Video 7: The cross-compiler toolchain
This video presents the different tools of the GNU gcc toolchain needed to build the embedded application binary file.
Video: Cross compiler toolchain
Video 8: The toplevel C++ code
This video explains in detail the C++ sourcecode of the toplevel. The instanciation of the SocLib components is thoroughly presented.
Video: Topcell C++ sourcecode
Video 9: The embedded application sourcecode
This video describes the various files used to build the embedded application.
Video 10: Shifting from the MIPS32 to the PPC405
This video shows how, in SocLib, it is possible to shift from one processor to another. It concludes this interactive tutorial.
