Description

The Sensoray Model 322 is a low-cost PC/104+ video graphics adapter that combines the functionality of a high-powered desktop graphics adapter to provide a powerful graphics solution for embedded applications. The 322 is suitable for high bandwidth video and multimedia embedded applications taking full advantage of the PC/104+ bus throughput, very wide video buffer memory, and multiple onboard video engines. The 322 uses the very latest in single chip video graphics controllers that offer low power consumption, enhanced reliability and ruggedness. The 322 is compatible with any PC/104+ compliant CPU board such as the Sensoray model 301-06.

The 322 has a 32-bit 3D video core which is 100% VGA compatible. It has outputs for a CRT monitor (RGB), LCD flat panel and two TV outputs. Using Dual View capabilities, two different applications can be displayed on different devices or a portion of the primary display on the secondary display.

VGA compatible

The 322 is fully VGA register compatible and can be used with any operating system that has a VGA drivers. A fully compliant VGA BIOS provides full compatibility with PC based systems. Enhanced drivers, available for Microsoft Windows 95, Windows NT, and Windows 98, extend the functionality of the 322 by using the high performance capabilities of the video graphics controller (the advanced user can access the higher capabilities of the 322 in other operating systems by writing an appropriate driver that accesses the graphic controller's registers.

Video memory

The Model 322 comes standard with 4 MB of high speed video memory on a 128-bit memory bus embedded in the controller chip.

CRT Interface

The 322 has a high speed, up to 135 MHz, pixel clock for CRT displays. This allows for very high resolution at high vertical refresh rates. For example a vertical refresh rate of 75 Hz at 1024x768 resolution or 85 Hz at 640x480. At 1600x1200 a refresh rate of 60 Hz is achieved.

The 322 also includes various features such as: LCD auto-centering, LCD screen expansion (including XY interpolation screen expansion), virtual refresh, and special dithering engines for TFT and DSTN flat panels. The LCD interface uses 3.3V voltage levels compatible with most low power LCD flat panels.

Graphics and Video Engines

A set of powerful graphics engines designed to accelerate 2D and 3D graphics. These engines include an IEEE floating point setup unit, a full featured 3D rendering engine, a 128-bit 2D drawing engine, a motion compensation block, and a video processor block. The drawing engine supports key GUI functions such as 3 operand ALU with 256 raster operations, pattern BLT, color expansion, trapezoid fill, and line draw. The IEEE Floating Point Setup and 3D rendering engines combine to give high end 3D graphics performance to embedded computer systems with such features as Mip Mapping, Alpha Blending, Anti-Aliasing, Specular Highlights, and Fog, supported. For MPEG decoding, the motion compensation engine can significantly reduce CPU overhead. The video processor block manages the video of different video data formats and can perform such conversion as YUV to RGB and perform flicker reduction and adjustable overscan/underscan for TV display.
