- Hi, I am compiling a survey on architecture support for advanced
- visually-oriented applications
-
- Some aspects of this survey are the following:
-
- 1. Support for graphics function in general-purpose processors.
- 2. Sp. purpose coprocessors that offload work from main processors.
- 3. Design choices in actual workstation systems ranging from Xterminals
- to advanced modeling/visualization engines.
-
- Some related areas include design of laser-printer engines / Postscript
- interpretors.
-
- Some of the microarchitecture issues are:
- =========================================
-
- 1. Techniques for optimizing frame-buffer access.
- > Sp. cache instructions, e.g., allocate-no-fetch as in 88110.
- > Small frame-buffer write-back cache with 1/60 sec flushing.
- > Tiling organization of frame-buffer for exploiting access locality.
- 2. Support for saturating arithmetic.
- 3. Packed pixel arithmetic.
- 4. Support for single-cyle x,y addressing.
- 5. TLB support for different page sizes.
- 6. Support for the special requirements posed by applications such as
- > MPEG
- > Display Postscript
- > 3-D graphics and viewing transforms
- > Gouraud/Phong shading
- > Real-time video processing
- > Speech recognition
