The VCU slave interface is accessed once per frame by the APU, which sends a frame-level command to the IP. This interface therefore does not require a fast data path. An interrupt is generated on conclusion of each frame. These commands are processed by the embedded MCU, which generates tile- and slice-level commands to the Decoder block hardware.
