Allegro DVT video IP codecs present in the Xilinx ZynqMP SoC. The IP core may
|
||
|
|
either be a H.264/H.265 encoder or H.264/H.265 decoder ip core.
|
||
|
|
|
||
|
|
Each actual codec engine is controlled by a microcontroller (MCU). Host
|
||
|
|
software uses a provided mailbox interface to communicate with the MCU. The
|
||
|
|
MCUs share an interrupt.
