AN3350 Application Note AN3350 Application note eTPU compiler tools Introduction This application note explains how to use eTPU build tools to build programs. The eTPU build tools translate source code into object code and then organize that object code to create a program that is ready to execute. The eTPU build tools run on the host system to generate software that runs on target systems (such as SPC563Mxx and SPC564Axx devices) which feature the eTPU peripheral. The host and target can be the same system, but usually the two are separate.

Copyright © 1997 - Carnegie Mellon University This research was sponsored by NCCOSC under Contract No. N66001-94-C-6037, Arpa Order No. B326. The views and conclusions contained in this document are those of the authors and should not be interpreted as representing the official poli- cies, either expressed or implied, of NCCOSC or the U.S. Government. Keywords: User Interface Development Environments, User Interface Management Systems, Constraints, Prototype-Instance Object System, Widgets, Object-Oriented Programming, Direct Manipulation, Input/Output, Amulet, Garnet. Abstract The Amulet User Interface Development Environment con- tains a comprehensive set of tools that make it significantly easier to design and implement highly interactive, graphical, direct manipulation user interfaces. Applications imple- mented in Amulet will run without modification on Unix, PC, and Macintosh platforms. Amulet provides a high lev- el of support, while still being Look-and-Feel independent and providing applications with tremendous flexibility. Amulet currently provides a low-level toolkit layer, which is an object-oriented, constraint-based graphical system that allows properties of graphical objects to be specified in a simple, declar- ative manner, and then maintained automatically by the system.
