NOTE
In this manual, assertion and negation are used to specify forc-
ing a signal to a particular state. In particular, assertion and as-
sert refer to a signal that is active or true; negation and negate
indicate a signal that is inactive or false. These terms are used
independently of the voltage level (high or low) that they repre-
sent.
The audience of this manual includes systems designers, systems programmers, and
applications programmers. Systems designers need some knowledge of all sections, with
particular emphasis on Sections 1, 5, 6, 7, 13, 14, and Appendix A. Designers who
implement a coprocessor for their system also need a thorough knowledge of Section 10.
