Overview

The C6Run project offers a suite of tools to make life easier for DSP-side development (targeting the TI C6 series DSPs, including the C64x+ on the BeagleBoard's OMAP3530). Among the offered tools are C6RunApp (which enables the developer to prototype code on the DSP using a simple cross-compilation script and running the resulting executable, with file system/console access) and C6RunLib (wrap DSP-side code into ARM libraries for easy access).

DSP-RPC-POSIX is a component of C6RunApp which allows you to do DSP->GPP remote procedure calls - that is, you can invoke functions/code residing somewhere on the GPP side directly from the DSP as if you were accessing a local function (there are, of course, certain requirements and restrictions).

Documentation

The project documentation has its own wiki page at http://elinux.org/BeagleBoard/GSoC/2010_Projects/C6Run/Documentation

Build Instructions

1. Checkout the sources from SVN

2. Change into the sources directory and issue make beagleboard_config

3. Set up dependency paths in the top-level Rules.mak and in platforms/beagleboard/Platform.mak

4. Issue make build

5. That's all! You can simply add the bin directory to your path and start doing things like c6runapp-cc hello_world.c -o hello_world


Since the RPC layer builds on top of the existing C6Run build system, nothing else is necessary for the build.
