Here are some early BMP manipulation chips designed by Cary D. Kornfeld while he worked at the famous Xerox PARC from 1981-1984
He then moved to Bell Labs (Western ELectric) where he continued such work

These chips apparently serve one purpose, rotating/manipulating BMPs, and are prototypes.
The method is described here:
