It enables and provides remote access to hardware acceleration for audio and video decoding on the IVA-HD in OMAP4-based platforms via a syslink/rcm shim layer accessing the OMAP's Codec Engine API codec interface on the co-processor (Ducati/M3) from the host under Linux without needing OpenMAX.[1][2][3] The "Ducati subsystem" comprises two ARM Cortex-M3 processors (CPUs), and the ASICs IVA-HD and ISS.[4]
Software supporting DCE
GStreamer uses the ASICs of Ducati
- gst-ducati, a GStreamer plugin for OMAP4 using libdce[2][5]
- omapfbplay, a video player for OMAP using Video4Linux (V4L)[6]
