Codec Engine 2.20 Release Notes
August 2008
This Codec Engine Release is targetted to the OMAP platforms,
enabling users to instantiate and utilize both local and remote codecs.
In addition to heterogenous devices (e.g. OMAP2530, OMAP3530, etc.),
it supports single processor environments as well; specifically C64+ devices
(e.g. DM643x, and DM648), ARM9 devices running Linux (e.g. OMAP3503) and x86
devices running Linux.
This release has not been validated on ARM-based DaVinci devices
(e.g. DM644x, DM6467and DM355), and may not operate correctly on them.

The Codec Engine is a software platform for algorithm execution that
satisfies the following, high-level goals:
- Robust - drives pre-integrated components with fully
characterized performance.
- Easy to use - app developers specify what needs to
be run, but not how or where.
- Extensible and Configurable - new algorithms can be added
by anyone, using standard tools and techniques.
- Portable - API's are target, platform, and in many cases
even codec independant.
Primary packages in this Codec Engine release are briefly described here.
(There are others, see the Configuration Reference
Guide documentation for a complete package list.)
- ti.sdo.ce - The Codec Engine runtime.
- ti.sdo.ce.video2 - The Codec Engine video 1.20 component
(supporting the xDM 1.20 interfaces). Both encode and decode
are supported, and an example is provided.
- ti.sdo.ce.video1 - The Codec Engine video 1.00 component
(supporting the xDM 1.00 interfaces). Both encode and decode
are supported, and an example is provided.
- ti.sdo.ce.image1 - The Codec Engine image 1.00 component
(supporting the xDM 1.00 interfaces). Both encode and decode
are supported, and an example is provided.
- ti.sdo.ce.speech1 - The Codec Engine speech 1.00 component
(supporting the xDM 1.00 interfaces). Both encode and decode
are supported, and an example is provided.
- ti.sdo.ce.audio1 - The Codec Engine audio 1.00 component
(supporting the xDM 1.00 interfaces). Both encode and decode
are supported, and an example is provided.
- ti.sdo.ce.osal - The Codec Engine OS Abstraction
Layer. This package insulates CE from the OS it's running on, and
provides a few Modules for customers to use (e.g. Memory).
- ti.sdo.ce.utils.trace - The Codec Engine utility
package for trace. This includes the TraceUtils module. This makes
tracing features easier to use by an application. It will be
supported in this release, but may be replaced in a future release
with an incompatible implementation.
Additionally, this release of the Codec Engine continues to support
the deprecated xDM 0.9 interfaces included in xDAIS 5.00. This
support is provided in the following packages:
- ti.sdo.ce.video - The Codec Engine video component.
Both encode and decode are supported, and an example is provided.
- ti.sdo.ce.image - The Codec Engine image component.
Both encode and decode are supported, and an example is provided.
- ti.sdo.ce.speech - The Codec Engine speech/voice
component.
Both encode and decode are supported, and an example is provided.
- ti.sdo.ce.audio - The Codec Engine audio component.
Both encode and decode are supported, and an example is provided.
Codec Engine is provided as non-rebuildable libraries. Source is
provided for debugging and educational value, but is not intended to be
modified. Modified sources will not be supported.

The following significant changes have been made since 1.00
2.20 (This Release)
- New features
- Added support for OMAP3530 and OMA2530
- Source code is provided for reference
- New default external memory map used by Codec Engine. See
ti/sdo/ce/ipc/dsplink/DspLinkCfg.xdc for details.
- New support for DSP/BIOS Link porting integration. See
ti/sdo/ce/ipc/dsplink/README.txt for details.
- Removed features
- Removed support for DaVinci ARM-based devices (DM644x, DM355
and DM6467). This is a temporary hiccup in the CE roadmap, but
was done to more quickly support OMAP customers. DaVinci device
support will be restored in a release later this year.

2.10
- New features
- Updated C6x libraries to CG Tools 6.0.16
- Added support for DM6467
- Added support for IVIDDEC2 interface.
- Added "experimental" asynchronous API support. Some customers have
requested support for asynchronous VISA APIs. This release provides
that support - with "experimental" quality. That is, the APIs are
supported, but compatibility in future releases may be broken or
removed/replaced completely. Customers should feel free to use these
APIs in products, but look for further guidance and roadmap advice
from TI as the product lifecycle continues.
- Updated Dependencies
- xDAIS 6.10
- Framework Components 2.10
- For codecs that acquire EDMA3 channels via IRES, FC
release notes state the appropriate, dependent EDMA3 LLD product
version.
- CMEM 2.10
- DSP/BIOS 5.32.01
- DSP Link 1.50
- XDC Tools 3.00.06
- The following defects were resolved:

Headline |
SDSCM00022558 |
Codec Engine build files and instructions should explain better
how to build for particular platforms only, specificallyDM355 |
SDSCM00022858 |
extern declaration of function table symbol is wrong in examples'
<codec>_ti.h files |
SDSCM00023298 |
VIDDEC1 doesn't provide enough buffers for CIF decode
(17 needed) |
- The following enhancements were resolved:
2.00
- New features
- In Linux-based applications, Codec Engine is now callable from
multiple processes. For environments that require DSP/BIOS Link
(e.g. DM644x), users must use Link 1.40.05 P3. For single
processor environments (e.g. DM355), no special instructions are
required. Note that, as always, codecs that
share resources must be configured into the same scratch group. These
scratch groups span processes - so if two different apps use codecs
that share resources, the system integrator must ensure they are placed
into the same system-wide scratch group.
- Support for the new IVIDTRANSCODE xDM API has been added. This
provides a standard API for invoking video transcoding algorithms.
See the Reference Guide for details.
- Added cache management configuration to xDM 0.9-based remote
image and video algorithms. Using this feature, it is possible to
configure these interfaces to not writeback the output data
buffers if, for example, these are being moved between internal and
external (shared) memory using DMA. This can significantly improve
performance of remote process() calls, as writing back large video or
image buffers is time consuming. See the Configuration Reference Guide,
specifically the
ti.sdo.ce.video.VIDDECConfig/.VIDENCConfig
(and similar modules in the ti.sdo.ce.image package) for
details.
- Applications can create remote instances of the same algorithm
to run at different priorities. This enables applications to have,
for example, background transcoding or encoding tasks running alongside
real-time encode or decode operations that use the same codec.
This is handled by adding the priority to the codec name during
creation (e.g. "mpeg3dec:4"). See the Application Developer's Guide
and API Reference Guide for details.
- Improved trace usability with new CE_DEBUG environment
variable. See the Application Developer's Guide for details.
- Updated Dependencies
- Updated to xDAIS 6.00

1.20
- General
- Updated to xDAIS 5.21, which includes xDM 1.00 interfaces
- Updated to DSP/BIOS Link 1.40.05 - this resulted in some
necessary configuration-related changes
- Updated to Framework Components 1.20.02
- Updated to new XDC Tools 2.93.01
- Updated to CMEM 1.04
- Added examples for single-processor, environments (e.g. DM643x) -
this includes placing executables into platform-specific directories,
as well as demonstrating necessary caching techniques for cache-enabled
environments.
- Added Link Arbiter Daemon (LAD)
- Added CERuntime_exit() for applications which want to erase any
CE Runtime from their environment without exiting their application.
This is useful if, for example, an application wants to switch between
a Codec Engine based environment, and a custom DSP Link-based framework.
- Moved examples into "Codec Engine-specific" namespaces (e.g., the
previous codecs.viddec1_copy codec package is now the
ti.sdo.ce.examples.codecs.viddec1_copy package).
- Added configuration option to xDM 0.9-based video encoders
to not manage the cache for the reconstruction buffers.
- Added 'checked' builds to the distribution. This enables
some parameter and usage validation to occur within the CE
framework, helping to identify common coding errors in both
applications and algorithms. Enabling this optional feature
introduces some performance overhead, but is encouraged for
those early in development. This can be enabled in the
application configuration, as well as the Server (for systems
with remote algorithms). See the documentation on the
ti.sdo.ce.Settings Module's "checked" parameter in the
Configuration Reference Guide.
- BIOS-based environments
- Added LOG_events for profiling performance
- The following defects were resolved:
ID |
Headline |
SDSCM00014413 |
xdcpaths.mak requires FC installation in ".lite" release |
SDSCM00014540 |
CE OSAL requires presence of dsplink.dsp package even if it's used
in a DSP/BIOS-only setting |
SDSCM00015336 |
Scale example's SCALE_Params struct does not have the required
IALG_Params struct as its first element |
- The following enhancements were resolved:
ID |
Headline |
SDSCM00013759 |
CMEM should support multiple processes |
SDSCM00014703 |
Add Memory_cacheWb() to OSAL |
1.10
- General
- Updated to C6x Codegen 6.0.7
- Updated to DSP/BIOS 5.31.01
- Updated to Framework Components 1.10.01
- Updated to xDAIS 5.10, which includes xDM 1.00 beta
interfaces
- CE Runtime
- Added new methods to ti.sdo.ce.ICodec interface
(getCreationStackSize(),
getDaramScratchSize(), and
getSaramScratchSize()) to make Server configuration
easier. When codecs implement these methods, the XDC Tools
are able to either:
- Auto-generate the DSKT2 scratch configuration, or
- Validate the scratch config (if the server integrator
wants to continue explicitly configuring those values).
- VISA
- Added support for xDM 1.00 Beta interfaces. (Previous xDM
0.9 interfaces continue to be supported)
- SPI (System Programming Interfaces)
- Added VISA_setContext() and
VISA_getContext() services for stub/skeleton/API authors.
- Documentation
- Added "Adapter" application note describing how to integrate
non-xDM codecs, as well as a technique for adding pre- and post-
processing steps to existing codecs without modifying them.
- Examples
-
Added new, Linux-only example demonstrating how users can
create a shared library from a single configuration, which can
then be used by multiple applications.
-
Added a new example, explicitly describing the steps taking
during configuration to better demonstrate the necessary
configuration steps for users who want to integrate this into
their own, custom build flows.
-
Modified example codecs, when possible, to utilize copy
codecs now distributed in xDAIS 5.10. In this way, it's more
clearly described what little XDC packaging is required to
integrate an already XDC packaged Codec (independant of CE) into
the CE framework.
- Defects
- SDSCM00010422 - CE and CMEM should set the close-on-exec
flag on any open file handles
- SDSCM00005810 - Additional C++ testing required
- SDSCM00004993 - GT no longer supports wildcards as second
character
- SDSCM00004805 - GT computes (a lot) during GT_?trace()
- Enhancements
- SDSCM00010364 - GT needs productized
- SDSCM00008121 - not possible to properly size RMS thread's
stack
- SDSCM00007887 - Support VISA_getContext/setContext SPIs
- SDSCM00006616 - CE should ensure unique UUIDs
- SDSCM00003992 - Add pre- and/or post- process example to
codecs
- SDSCM00002920 - ICodec should have a getScratchSize method
1.02
- General
- Introduced ti.sdo.ce.utils.trace.TraceUtils
module.
- Libraries are now provided in release builds. Previously,
they were debug-only.
- Introduced Engine_setTrace() API.
- Added support for C++
- VISA Classes
- Added extended xDM support to the remaining 3 classes
(AUDENC, VIDENC, and SPHENC).
- Documentation
- Addition of System Programming Interface (SPI) Reference
Guide.
- Codec Engine Server Integrator's Guide (SPRUED5)
- Codec Engine Algorithm Creator User's Guide (SPRUED6)
- Minor updates to the Codec Engine Application Developer's
Guide (SPRUE67A)
1.01
- General
- Many trace strings were modified/added.
- C64P libraries built with 6.0.3 compiler.
- VISA Classes
- Audio Encoding support has been added
- Better compliance checking of "size" field. This field
must be set correctly in the various VISA APIs, as it is
now used to determine how much data to provide to the
codecs.
- Related to previous bullet, added extended xDM support to
VIDDEC, VIDENC, AUDDEC, IMGDEC, and SPHDEC classes. There are
limits to the size of the extended structures, and they must not
contain pointers in the extended structures.
- outArgs fixed to be provided in the case of a failed
process() call (enabling inspection of extendedError).
- Removed cache alignment validation of input buffers. When the
application can ensure cache coherence, these buffers need not be
aligned.
- Documentation
- Minor updates to the Codec Engine Application Developer's
Guide (SPRUE67A)
The Codec Engine packages are available in the "packages/"
subdirectory of the product. If you have a previous release of the

Compatibility Key Definitions
Compatibility keys are intentionally independent of Marketing product
numbers and are intended to:
- Enable tooling to identify incompatibilities between components,
and
- Convey a level of compatibility between different releases to
set end user expectations.
Compatibility keys are composed of 3 comma-delimited numbers - M,S,R
- where:
- M = Major. A difference in M indicates a break in
compatibility.
- S = Source. A difference in S indicates source
compability. That is, the user's source doesn't require change, but
does require rebuilding.
- R = Radix. A difference in R indicates an introduction
of new features, but compatibility with previous interfaces has not
broken. If libraries are provided by the package, an application
must re-link with the new libraries, but not rebuild from source.
