D-37C - Programming

Programming

The computer uses a full 24 bit instruction word and data word. Data is represented in one of two fashions, as a 23 bit binary fraction (full word) or as a 10 bit fraction (split word). The two formats are shown in the figure. Instructions also have two formats, either flagged or unflagged as indicated in the figure. A list with all of the available instructions with numeric and mnemonic codes follows. For more information on programming see:
