Back to the Future 100?

摘要

In a 1968 article titled, On the Design of Display Processors, Meyer & Sutherland describe their experiences in designing a display processor to optimize the performance of the graphics display operations and the I/O channel between a display and the CPU:rnWe approached the task by starting with a simple scheme and adding commands and features that we felt would enhance the power of the machine. Gradually the processor became more complex. Finally the display processor came to resemble a full-fledged computer with some special graphics features. And then a strange thing happened. We felt compelled to add to the processor a second, subsidiary processor, which itself began to grow in complexity. It was then that we discovered a disturbing truth.
