4.3.5. Nanovolt Detector Software.
The control program within the nanovolt detector controls the operation of the nanovolt
analog interfaces and communication interfaces from the nanovolt cpu microprocessor.
The major hardware interfaces to the nanovolt detector microprocessor are the fibre-optic
interface (and ultimately the 6675A user) to the 6675A cpu, and the analog to digital (also
analog input amplifier) converter.
The nanovolt detector control program is approximately 42 thousand bytes long. It is
written in the "C" programming language and stored as binary numbers in the 27C512 read
only memory.
