Validation Information
This release was built and validated using the following tools:
Build Tools (included in Processor SDK RTOS Automotive):
- C7000 Code Generation Tools version: 1.0.0
- C6000 Code Generation Tools version: 8.2.4
Dependencies (included in Processor SDK RTOS Automotive):
- VXLIB version: 1.1.3.0
- TIDL version: 0.8.0.0
- Imaging version: 0.8.0.0
- Processor SDK RTOS Automotive version: 0.8.0.0
Dependencies (NOT included in Processor SDK RTOS Automotive):
- GCC: 5.4.0
- libpng: 1.2
Fixed Issues
- TIOVX-539: Framework should provide image as input to display node when actual input is object array
- TIOVX-547: Generated kernels with array parameters use item size rather than type for error checking
- TIOVX-553: PyTIOVX LUT query fails
- TIOVX-554: PyTIOVX generates two different incrementers when Pyramid and object array types are used
- TIOVX-573: Graph verify does not detect in and out nodes for replicated parameters
Known Issues
- VXLIB-371: Multiply iS16 iS16 oS16 with 1/255 as scaling factor fails for X86 target
- TIOVX-24: Some Harris Corners test cases fails for when running entire test suite
- TIOVX-164: In x86_64, some replicate with Pyramid testcases fail
- TIOVX-207: tivxMaxNodes test case is failing in x86_64 PC emulation
- TIOVX-519: tivxGraphPipelining.testLoopCarriedDependency is failing
- TIOVX-569: Bmp utils does not load RGBX properly

Package Versioning
Each package version is composed of 4 period-delimited numbers - represented here by the letters M, m, p and b [M.m.p.b]
. The table below provides a descriptive reference regarding package version numbering.
Digit | Meaning | Description |
---|---|---|
1 (M=Major) | Major revision | Incremented when the new version is substantially different from the previous For example, a new module added or an existing module's algorithm significantly altered. |
2 (m=minor) | Minor revision | Incremented when the new version has changed but not in a major way. For example, some minor changes in the API or feature set. |
3 (p=patch) | Patch number | Incremented for all other source code changes. This include any packaging support code. |
4 (b=build) | Build number | Incremented for each release delivery to CM. Reset for any change to M, m or p |
