    TAYRA - A 3D Graphics Raster Processor
    (The Eurographics Association, 1996) Waller, Marcus; Dunnett, Graham; Bassett, Mike; MCCann, Shaun; Makris, Alex; White, Martin; Lister, Paul; Bengt-Olaf Schneider and Andreas Schilling
    This paper describes the Junctionality oj a 3D Graphics Raster Processor called TAYRA. TAYRA consists in the most part oj Graphics Raster Pipeline with five major external interfaces: PCI Master/Target, Depth, Texture, Colour and Video Interfaces.The Graphics Raster Pipeline perform'S' all the major OpenGL style (not necessarily compliant) raster functions: scan conversion; lines, spans, triangles, rectangles, perspective correction o f texture coordinates. mip map jevel selection, and many other texture modes, alpha blending, and other Junctionalities. Further, through TAYRA's fast host to buffer access mechanisms it can do advanced stencilling, multi-pass antialiasing, and other algorithms; all accelerated in hardware with a sustained pixel write speed of 29 MPixels/sec (peak of 33 MPixels/sec). This translates to a peak 25 pixel triangle drawing speed of 890K Triangles/sec, limited bv PCI bus bandwidth.

    An Advanced 3D Frame Buffer Memory Controller
    (The Eurographics Association, 1996) Makris, "Alex; White, Martin; Lister", Paul; Bengt-Olaf Schneider and Andreas Schilling
    This paper details the design o f an advanced 32 bit 3D frame buffer memory controller for a 3D Graphics Raster Processor called TAYRA [1]. This memory controller is designed to provide a performance o f 33 MPixelsls for read and write cycles, 4 GPixelsls for block write, and 16.5 MPixelsls for read, modify, write cycles (with a pixel size o f 4 bytes). This performance is without any interleaving. It has several control modes: S3 shared frame buffer protocol compatibility [2], stand alone 3D buffers, multiplexed 2DI3D buffers, and others. Further, our 3D memory controller is designed to control DRAM, VRAM and WRAM, and EDO versions of these memories. Also, we support up to 4 screen buffers, 16 MBytes o f screen memory, and many combinations o f memory organisationsup to 1600x1280.
