STA1295, STA1275

System description

106

The main features are:

•

Video overlay

•

Supported color formats:

RGB565, ARGB8888, YUV422, YUV 420 PLANAR

•

Gamma correction (using independent look-up tables for R, G, B)

•

Dithering

•

Configurable alpha blending modes, with either buffer alpha or constant alpha

2.6

Touch screen controller

Embedded 10-bit resistive touch screen controller allows to control 7-inch display touch

screens.

2.7

Video Input Port

The Video Input Port (VIP) allows to grab images from external devices, supporting parallel

CCIR-656 interface up to 54 MHz. Both embedded synchronization and external

synchronization are supported. VIP supports both interlaced or progressive modes.

The VIP is synchronized with display controller to prevent tearing effects, and is used in

conjunction with SGA to implement on the fly YUV to RGB color conversion and bilinear

interpolated re-scaling.

2.8

3D graphics engine

STA1275 and STA1295 come with a powerful 3D, allowing smooth HMI rendering with

impressive transition effects quality, as well as navigation and instrument clusters rendering.

The 3D engine is based on a unified shader architecture, based on an ultra-threaded SIMD

processor that performs as both vertex shader and fragment shader with IEEE 32bit floating

point full precision. When used as a vertex shader it performs geometry transformations and

lighting computations. When used as a fragment shader it applies texture data and

computes color values for each pixel.

The main features are:

•

OpenGL® ES 2.0 / 1.1 compliance, including extensions; OpenVG™ 1.1

•

IEEE 32-bit floating-point pipeline

•

Ultra-threaded, unified vertex and fragment (pixel) shaders

•

Low bandwidth at both high and low data rates

•

Low CPU loading

•

Up to 12 programmable elements per vertex

•

Dependent texture operation with high-performance

•

Alpha blending

•

Depth and stencil compare

•

Point sampling, bi-linear sampling, tri-linear filtering, and cubic textures

•

Resolve and FastClear

•

8k x 8k texture size and 8k x 8k rendering target
