- This paper is recommended reading for anybody with an
- interest in architecture, with or without graphics, since
- the insights are quite applicable to the design of any
- special purpose HW "accelerators".

- "On the Design of Display Processors",
- CACM, Vol.11, No.6, June 1968

- The abstract (typos are mine):
- The flexibility and power needed in the data channel
- for a computer display are considered. To work
- efficiently, such a channel must have a sufficient
- number of instructions that it is best understood as a
- small processor rather than a powerful channel. As it
- was found that successive improvements to the display
- processor lie on a circular path, by making
- improvements one can return to the original simple
- design plus one new general purpose computer for each
- trip around. The degree of physical separation between
- display and parent computer is a key factor in display
- processor design.
