ABSTRACT:
An embodiment of the present invention combines, on a single integrated circuit, an eight channel GPS receiver, a 68330-type microprocessor, a 68681-type DUART serial communications controller, an analog-to-digital converter, a real-time clock, a random access memory and a boot read-only memory. A system integration module and inter-module bus allow tri-state control of the microprocessor such that a commercially available 68332-type emulator may be used for software development.
