2.10.3 SSP/SPI ports supporting
Motorola SPI-compatible interface
Texas Instrument synchronous serial interface
National Semiconductor MICROWIRE® interface
Unidirectional interface
– DMA capability
2.11 Video input port (VIP)
The Video Input Port (VIP) allows to grab images from external devices, supporting parallel
interface up to 54 MHz. Both embedded synchronization and external synchronization are
supported. VIP supports either interlaced or progressive mode.
The VIP is synchronized with display controller to prevent from tearing effects, and is used
in conjunction with SGA to implement on the fly YUV->RGB color conversion and bilinear
interpolated re-scaling.
2.12 Smart graphics accelerator (SGA)
The aim of the Smart Graphic Accelerator (SGA) is to provide an efficient 2D and 3D
primitive drawing tool that breaks down the MIPS and power consumption concerns of pixel
processing.
It supports:
Control and synchronization features
2D-graphic features
Video overlay features
3D graphic features
2.13 Display controller
The main features of the LCD Controller are:
Supports single and dual panel monochrome and color STN displays up to 8 bits
interfaces
Supports single and dual panel color STN displays with 8 bits interfaces
Supports TFT, AD-TFT and HR-TFT color displays
Resolution programmable up to 1024 lines of 1024 pixels
12-bpp (4:4:4), 15+I bpp (I:5:5:5) or 16 bpp (5:6:5) true-color
24-bpp packed and non-packed true-color (non-palettized)
Color enhancement (16-bpp to 18-bpp conversion) for addressing 18-bit (RGB 666)
TFTpanels using only 16-bpp resolution
