Single bit storage and retrieval with transition intelligence

摘要: A peripheral processor for a central processing unit is in the form of memory which repetitively loaded with data scanning an array. The performs predefined logical operations between respective elements successive scans data. Preferably address signals sent to via preassigned set lines specify desired one plurality predetermined operations. Logical may also be performed when written as well read from processor. shift register, example, automatically transfers original present scan past new into memory. In field machine control, permits single-bit storage and retrieval respect byte oriented detects individual bit transitions, thereby facilitating manipulation single input/output conditioning control based on occurrence transitions.
