Interfaces, Subroutines, and Programs for the Grinnell GMR-27 Display Processor on a PDP-11/45 with the UNIX Operating System

Abstract

The specialized device interfaces for the University of Maryland Computer Vision Laboratory image acquisition and display equipment extend the capabilities of a PDP-11/45 hosting the UNIX operating system. The devices include the Grinnell GMR-27 color display processor, the other Computer Vision Laboratory display and scanning equipment, and the Digi-Data TM-11/TU-16 compatible tape drive. Subroutine packages give easy access to the interfaces from user programs, allowing full use of the special features. Programs using these subroutine packages and the well-designed UNIX operating system provide a flexible and powerful environment for image processing and program development. Short descriptions of these interfaces, subroutines, and programs are given for program writers and other users.
