Producer

A producer block provides the following interactions with the application producer component:

• During setup phase:
  • Synchronization:
    • Accepts producer synchronization requirements.
    • Reports consumer synchronization requirements.
    • Accepts producer allocated sync objects.
    • Reports consumer allocated sync objects.
  • Buffers
    • Accepts list of element attributes producer can generate.
    • Reports consolidated packet attribute list.
    • Reports all allocated packets.
• During streaming phase:
  • Signals availability of packets for reuse.
  • Retrieves next packet to reuse with fence to wait for before writing.
  • Accepts filled packet with fence to wait for before consumer should read.
• In non-safety builds, during streaming phase:
  • Accepts limited changes to requested element attributes (e.g., to modify the image size).
  • Reports updated packet attributes.
  • Reports removal of buffers allocated for old attributes and addition of new ones.
