--The cycle time of microinstruction is increased because of the additional multiplexers But, in general, as the number of microinstructions is decreased the general throughput of the algorithm is also decreased.
In This proposed method, the microinstructions are divided into subsets, and thus the Numbers of microinstructions are apparently minimized and the throughput time of the automation is reduced.
The Combined Microinstructions (CMI) are used in MicroProgram Memory (MPM).
To reduce the number of microinstructions a new additional addressing circuit is suggested based on dividing the logical conditions into two subsets.
To reduce the number of microinstructions, an additional addressing circuit is proposed.
Therefore the main idea is to divide the microinstructions into two subsets as below:
To realize MPM, the field FLC of microinstructions should contain only three codes 01, 10 and 00 corresponding to X7, X3 and the unconditional transition (UnT) respectively.
In analyzing the classical method of synthesizing the automaton with combined addressing microinstructions using the ASM [G.sub.1], the following parameters can be stated:
