A frame buffer architecture is presented that reduces the overhead of frame buffer updating by three means. First, the bit-map memory is (x,y) addressable, whereby a string of pixels can be accessed in parallel. Second, the pixel-change operation is performed by hardware in a single read-modify-write cycle. Third, multiple objects in the frame buffer are addressable simultaneously by a set of address registers. The remaining task of generating (x,y) addresses and providing new data can be… 
The 8 by 8 display
TLDR
A simple model is developed to compare the performance of the 8 by 8 memory system with conventional frame-buffer organization, and execution traces of Smalltalk display programs are applied to the model to obtain figures of merit for different hardware organizations.
Architectures and algorithms for parallel updates of raster scan displays
TLDR
The symmetric square organization which allows the access of square regions of the display is advocated which is shown to be indeed better than the scan-line organization.
High Speed Image Rasterization Using a Highly Parallel Smart Bulk Memory
TLDR
A processor is described which uses VLSI architecture to rasterize lines, polygons and text quickly, providing the rasterization support required in high performance graphic raster displays and fast page printers.
PixelStamp graphics subsystems for the DECstation 5000
TLDR
The authors describe the architecture of the PixelStamp rendering processor and the implementation of that architecture for the DECstation 5000 Model 200 and an upgrade from the PXG-8 module to give 24 planes of color information, double buffered.
Vax Station: A General-Purpose Raster Graphics Architecture
TLDR
The raster graphics architecture is an extension of the RasterOp model and supports operations for rectangle movement, text writing, curve drawing, flood, and fill and is intended for implementation by both closely and loosely coupled display subsystems.

TLDR
The introduction of the FBP as a co-processor to geometry and video processors would increase efficiency and speed of graphics systems and bitmap workstations.

TLDR
A new bitmap graphic hardware component, the "image prism" which enables us to implement all orthogonal transformations with minimum processor and memory activity, and a new algorithm, which is significantly faster than previously known techniques, is outlined.
Hardware/software trade‐offs for bitmap graphics on the blit
TLDR
This paper explains the paradox of the Blit by referring to some principles of design: the hardware and software should be designed together to complement each other; carefully designed software can outperform infelicitous hardware; and simplicity of design leads to efficiency of execution.

TLDR
Advances in image generation hardware haven't fundamentally changed what an individual can actually do in an application; in contrast, some graphics hardware advances have created fundamental changes.
The SUN workstation architecture
TLDR
The report discusses the architecture and implementation of the Sun workstation, gives the background and goals of the project, contemplates future developments, and describes in detail its three main components: the processor, graphics, and Ethernet boards.
