The Display Subsystem (DSS) is a flexible, multipipeline subsystem that supports high-resolution display outputs. DSS includes input pipelines providing multilayerblending with transparency to enable on-the-fly composition. Various pixel processing capabilities are supported, such as color space conversion and scaling, among others. DSS includes a Direct Memory Access (DMA) engine, which allows direct access to the framebuffer (device system memory). Display outputs can connect seamlessly to an Open LVDS Display Interface transmitter (OLDITX), or can directly drive device pads as a Display Parallel Interface (DPI).
