Product Specifications

Technical details and manufacturing context for Scan Converter / Rasterizer Core

Definition

The Scan Converter / Rasterizer Core is a specialized processing core within a rasterizer system responsible for the fundamental scan conversion process. It transforms mathematical descriptions of shapes, lines, and curves into discrete pixel data by determining which pixels should be illuminated or colored to represent those graphical elements on a raster display or in a bitmap image. This core is a component used in computer, electronic, and optical product manufacturing, typically integrated into graphics processors, display controllers, or embedded systems. It operates on geometric primitives such as points, lines, and polygons, along with associated attributes like color, texture coordinates, and depth. The core performs scan-line algorithms or other rasterization techniques to determine pixel coverage, applies interpolation for attributes across the primitive, and outputs a stream of pixel fragments with color, depth, and other data for subsequent processing stages such as fragment shading and blending. The core is fabricated on silicon using CMOS process technology, with process nodes ranging from 28 to 65 nm. It supports a maximum resolution of 1920 to 3840 pixels, a pixel clock rate of 25 to 300 MHz, and a rasterization rate of 1 to 4 Gpixels/s. It interfaces with common display interfaces such as LVDS, MIPI, and RGB for both input and output. Operating voltage ranges from 1.8 to 3.3 V, power consumption from 0.5 to 2.5 W, and operating temperature from -40 to 85 °C. Package options include QFN, BGA, and LQFP, with pin counts from 48 to 256 and weight from 1 to 10 g. These values are reference ranges and must be verified for the specific model and application. Always confirm model-specific specifications and standards with the legal manufacturer or supplier.

Working Principle

The core receives geometric primitives (points, lines, polygons) with associated attributes. It performs scan-line algorithms or other rasterization techniques to determine pixel coverage, applies interpolation for attributes like color and texture across the primitive, and outputs a stream of pixel fragments with color, depth, and other data for subsequent processing stages like fragment shading and blending.
