  • ve2-xc2ve3558 based Platform Support — VVAS 6.3 is supported on VEK385 (Rev-A and Rev-B) and ve2-xc2ve3558 based platforms. The start-column property accepts values 0–32 on VEK385 (36 NPU columns) and 0–20 on ve2-xc2ve3558 (24 NPU columns).

  • HCWNC8 Tensor Format — added RGBX INT8, BF16, and FP16 variants for the HCWNC8 tensor layout. See Custom AI Tensor Formats.

  • Boolean Config Parsing — JSON config files now accept native booleans (true/false) and integers (1/0) interchangeably for all boolean parameters.

  • Letterbox Bounding Box Mapping — detection bounding boxes in letterboxed (Pre-processing IP resized) frames are now correctly mapped back to the source frame; previously the scaler geometry was not propagated to vvas_xmetaaffixer, causing bbox offsets.
