Abstract

A high-speed digital sequencer has been developed for controlling the new generation of 58 x 62 pixel format IR imaging devices. The design features a 92-bit x 1K RAM control-store memory and runs at 10 MHz. The controller is unique in that 34 signals are made directly available to an external device for use in sequencing the clocking of the detector. A Forth program for assembling user-defined code sequences has been written to assist in programming the controller. The Forth cross assembler runs on a DEC PDP or LSI-11 computer and generates downloadable microcode which can be readily changed.
