Export and Import Extension to OpenVX 1.1


Provide a way of exporting and importing pre-verified graphs or other objects, in vendor-specific formats.

Use Case

  • Embedded systems using fixed graphs, to minimise the amount of code required.
  • Safety-critical systems where the OpenVX library does not have a node API.
  • CNN extensions which require the ability to import binary objects.

Variations of This Extension

Some of the following requirements apply separately to Safety-Critical and Non-Safety-Critical implementations. These are annotated [SC] and [Non-SC] respectively.

A separate section lists those requirements that may be treated as a subset of the extension for the purposes of providing a smaller, more easily verified “deployment” implementation.

Implementations may optionally provide variations of this extension which allow import and export in defined formats, for portability purposes.
