Modular computer design with picoprogrammed control
J. G. Valassis · 1967
The subject computer is a 16-bit, one microsecond, integrated circuit computer implemented with picoprogrammed internal control. (Picoprogramming is conceptually comparable to microprogramming but without the need for decoding logic.) The design provides for modular CPU expansion both in word-size and instruction-repertoire. In addition, it lends itself very admirably to post-design tailorability, which is the most important unique feature of its picoprogrammed control design.
