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
