Memory-Span Concepts and the Synthesis of Sequential Machines in Feedback Shift-Register Form

  title={Memory-Span Concepts and the Synthesis of Sequential Machines in Feedback Shift-Register Form},
  author={Robert L. Martin},
Various procedures have long been known for synthesizing a sequential machine with a feedback shift-register if each state is to have exactly one assignment; however, these approaches fail if each state is allowed to have more than one assignment. Herein lies the equivalent-state problem. The equivalent-state problem is approached by establishing a relationship between feedback shift-register realizable flow tables and finite memory-span. From this relationship, a necessary and sufficient… 
A Multimodel and Computer Oriented Methodology for Synthesis of Sequential Discrete Systems
The synthesis of sequential discrete systems involves two major steps: 1) the abstract synthesis that yields a state-transition diagram, and 2) the structure synthesis that yields a realization. The

Any flow table M, which describes the circuit action of a normal fundamental mode asynchronous sequential circuit, can be realized as a fundamental mode circuit with feedback index [log 2 S], where S is the maximum number of stable states in any input column of M.
