Suitable for the Iyonix only
Provides various hardware acceleration and cacheing to speed up desktop graphical operations.
* Drawing window background textures.
* Drawing window furniture.('Toolsprites')
* Sprite plotting, especially large sprites such as backdrops and camera images. (uses DMA hardware to plot the sprite 3-5 times faster than the OS sprite plotting routines can manage.)
* Sprites are remembered in off-screen video memory, so that they can be plotted again much more quickly. (this helps large Filer windows and applications that use a lot of sprites such as !Paint.)
* Rendering of web pages in NetSurf and Firefox via Tinct (uses the DMA acceleration for large images/pages, and faster sprite plotting for rotated/swapped modes)
* Redrawing of window as other windows are moved around. Window contents are remembered (cached) in the extra video memory on the graphics card(s) so that they can be redrawn much more quickly when another window is moved across them.
This makes complex applications such as ArtWorks, Oregano2, PDF, NetSurf and others much smoother in use.
* Selecting rows and columns in !Paint. (rectangle inversions are performed using the hardware and are hundreds of times faster than doing them in software with RISC OS 5)
* Drawing horizontal and vertical lines (eg. window borders).
The acceleration feature is especially helpful in portrait modes and R/B swapped modes (as required for DVI/composite outputs and unmodified analogue RGB outputs) because all of the acceleration code knows about these features.
It can therefore accommodate them directly rather than using the software emulation that must be used when the OS does the rendering.
