Controls Integration
Tom Shea

Abstract
This lecture will begin with a definition of what an accelerator control system is, and importantly, what it is not. We will then review the control system architectures that are currently in use at the larger accelerator facilities. This discussion will naturally lead to identification of the major subsystems and their interfaces. We will explore general strategies for interfacing intelligent subsystems and then discuss issues specific to DSP implementations based on gate arrays and programmable DSPs. The following topics will also be covered: physical packaging; timing and synchronization; local and global communication technologies; interfacing to machine protection systems; remote debugging; configuration management and source code control; and integration of commercial software tools. Several practical realizations will be presented.
