5.10
- Introduction of XDM 1.00 Beta.
- The Reference Guide has been updated to include these Beta
APIs.
- Added "What's New in XDM
1.00" documentation, describing the high-level changes in the
XDM 1.00 Beta specification.
- This XDM 1.00 Beta spec addresses the following items:
- SDSCM00004685 - XDM speech enc and dec OutArgs should
have extendedError field for consistency
- SDSCM00005009 - IIMGDEC_OutArgs bytesconsumed should be
camelCase
- SDSCM00005245 - Video enc interface needs to reconsider
reconBufs conventions for RPCs
- Addition of example "copy" codecs, conforming with XDM 1.00 Beta
interfaces.
- Addition of example G.711 algorithm, conforming with XDM 0.90
speech encoder interface. This example shows how to wrap an XDM
interface around an existing algorithm.
- Addition of example "extended" video encoder copy codec. This
example shows how an algorithm can extend the XDM interface to
implement codec-specific features.
- SDSCM00005726 - Add doxygen comments to ialg.h
- SDSCM00005728 - IDMA3 channel object documentation needs to
include scratch environment support
- SDSCM00010925 - XDM User's manual uses XMI in places
- SDSCM00011274 - XDAIS header files for c55 need to include fully
qualified package files
The XDAIS packages are available in the "packages/"
subdirectory of the product. If you have a previous release of the
XDAIS product, you can install this release next to it, and
modify your builds to use this newer release.
If you're using the DVEVM, this can be done by setting the
XDAIS_INSTALL_DIR variable in the Rules.make file at the
top of the DVEVM distribution directory.
Compatibility Breaks!
None
Note, if you're upgrading from a release earlier than XDAIS 6.23, be
sure to review the Upgrade section for each of the releases between
your current XDAIS release and this one. Previous release notes are
available in the relnotes_archive directory.
The details provided below describe each package's compatibility with the
previous release (6.23).
-
ti.xdais - This package is compatible with the
previous release. (Compatibility key: 1,2.0,1 -> 1,2.0,1)
-
ti.xdais.dm - This package is compatible with
the previous release. (Compatibility key: 1,0,5 -> 1,0,5)
-
Compatibility with previous releases is not currently managed in
the examples.
If migrating from a release prior to XDAIS 6.23, consult previous
releases available in the relnotes_archive directory.
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.
This release was validated against using the following components:
- XDC Tools 3.10.05.61
- The examples were built with the following toolchains. Note
that, in general, nothing prevents them from being built with a
different version of tools, nor for other devices - they are
intentionally written in generic C):
- gnu.targets.Linux86 - 4.1.0
- gnu.targets.UCArm9 - 4.2.1
- gnu.targets.arm.GCArmv5T - 4.2.1
- microsoft.targets.arm.WinCE - 14.01.60511
- ti.targets.C28_large - 5.1.2
- ti.targets.C55P_byte - 4.0.0
- ti.targets.C55_huge - 3.2.2
- ti.targets.C55_large - 3.2.2
- ti.targets.C64P - 6.0.16
- ti.targets.C674 - 6.1.5
- QualiTI
- Rule 15 - Each XDAIS-compliant algorithm must be packaged in an
archive which has a name that follows a uniform naming convention - has
been disabled.
XDAIS examples and instructions are located in the
"examples" directory.
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. xdais_6_24.
Subsequent releases of patch upgrades will be identified by the patch
number, ex. XDAIS 6.24.01 with directory xdais_6_24_01.
Typically, these patches only include critical bug fixes.
