FSM-Based Models of Control Units,d FSMs. Classical principles are discussed for logic synthesis of Mealy and Moore FSMs. The FSM logic circuits are implemented with using system gates. The methods of preliminary assessment of hardware amounts are discussed in the last part of the chapter.

BIAS

Synthesis of Mealy FSMs with Counters,al and extended linear chains of states. Next, there is discussed the case of synthesis for regular GSA having a single chain of states. There are proposed different models of counter-based Mealy FSMs based on combining together known and proposed methods of structural decomposition.

headway

Mixed Encoding of Microoperations,mposition for synthesis of the FPGA-based combined FSMs. At last, it is discussed the mixed encoding of microoperations for LUT-based Mealy FSMs. It is proposed to form the collections of microoperations for elements of both parts of the partition of the set of microoperations.

anthesis

Combining Twofold State Assignment with Replacement of Logical Conditions,oth Mealy and Moore FSMs. Also, it is shown how to combine these two methods with encoding of the collections of microoperations. The last part of the chapter is devoted to synthesis methods based on transformation of initial GSA.

熄灭

defenses

Twofold State Assignment for Moore FSMs,of microoperations. The last part of the chapter is devoted to combining the twofold state assignment with encoding of the fields of compatible microoperations. There are proposed structural diagrams of FSM circuits. The examples of synthesis are given for majority of proposed FSM models.
