Namco System 22
From Wikipedia, the free encyclopedia
The Namco System 22 is the successor to the Namco System 21 arcade system board co-designed with the assistance of graphics & simulation experts Evans & Sutherland. It was first released in 1993 with the game Ridge Racer. It was essentially a continuation of the System 21 hardware design, where the main CPU provides a scene description to a bank of DSP chips which perform all necessary 3D calculations. Additional graphical improvements included texture mapping, Gouraud shading, transparency effects, and depth cueing thanks to the Evans & Sutherland 'TR3' chip/chipset, which stands for: Texture Mapping, Real-Time, Real-Visual, Rendering System.
A variant of the system, called the Super System 22, was released in 1995. The hardware was largely similar to the System 22, but with a slightly higher polygon rate and more special effects possible.
Both Super System 22 and System 22 can render significantly better graphics, more polygons with sharper texture-mapping, running in higher resolution and at a higher framerate compared to the graphics capabilities of the original Sony PlayStation, the Sega Saturn and the Nintendo 64 video game systems, but much less than what the Sega Dreamcast can produce.
