The HDMI 1.4/2.0 TX Subsystem driver abstracts the included supporting elements and provides you with an API for control. The API can be easily integrated into your application thereby providing an out-of-the-box solution.
The subsystem driver is a bare-metal driver, which provides an abstracted view of the feature set provided by each sub-core. It dynamically manages the data and control flow through the processing elements, based on the input/output stream configuration set at run time. Internally, it relies on sub-core drivers to configure the sub-core IP blocks.
