IVA-HD Sharing Design

GUID-20200825-CA0I-2FZS-BBZD-5QFMCGSTHXHP-low.gif Figure 2-1 New IVA-HD Sharing Concept

Sharing the IVA-HD hardware requires that the driver can only be called in M4. Both of PSDKLA and VSION SDK have their own Framework-components and codec. They are not compatible. The better way is to use one framework and codec, and make this framework and codec compatible with another.

The IPUMM and VISION SDK decode links run on the same core. As shown in Figure 2-1, since the frame-components support multi-instance, the IVA-HD can be controlled by the two entities, both gstreamer decode plugin and decode link can call the frame-components.

  • This document uses PSDKLA framework components instead of VISION-SDK framework components
  • The decode link uses the IPUMM codec to replace the VISION SDK codec
