This IPC Release is targeted to SYS/BIOS 6-based platforms.
Introduction, Documentation, What's New, Upgrade Info, Compatibility Information, Device Support, Validation Info, Known Issues, Examples, Version Information, Technical Support.
The IPC product provides software connectivity between multiple processors. Each processor may run either an HLOS (e.g. Linux, QNX) or an RTOS (e.g. SYS/BIOS).
The IPC product is comprised of the following
These components are provided as source code and prebuilt libraries.
The following documentation is available:
In addition, users are encouraged to monitor (and contribute to!) the TI Wiki.

The IPC packages are available in the "packages/" subdirectory of the product. If you have a previous release of the IPC product, you can install this release next to it, and modify your build scripts/makefiles to use this newer release.
Note, if you're upgrading from a release earlier than IPC 3.00, be sure to review the Upgrade section for each of the releases between your current release and this one. Previous release notes are available in the relnotes_archive directory.
This release supports the following devices (though examples are not provided for all):
This release was built and validated against using the following software components. Please use the versions below, or compatible:
This release was validated using the following hardware platforms (though others are supported):
This product's version follows a version format, M.mm.pp.bb, where M is a single digit Major number, mm is 2 digit minor number, pp is a 2 digit patch number, and b is an unrestricted set of digits used as an incrementing build counter.
To support multiple side-by-side installations of the product, the product version is encoded in the top level directory, ex. ipc_3_23_00_01.
Subsequent releases of patch upgrades will be identified by the patch number, e.g. IPC 3.22.01.XX with directory ipc_3_22_01_XX. Typically, these patches only include critical bug fixes.
