Logic machine architecture

The production of uniformity in the field is best grasped, however, through the logic of mechanization. As factor prices in the West have, since at least 1950, favored the substitution of farm machinery for hired labor, the farmer has sought cultivars that were compatible with mechanization. That is, he selected crops whose architecture did not interfere with tractors or sprayers, which ripened uniformly, and which could be picked in a "once-over pass of the machine. 

The System Logical Level at which the safety functions are allocated to the various elements of the system logical architecture, plus the tasks to be performed by generic human-operator roles - the causes of the hazards are identified at this level, as are the Safety Integrity Requirements that limit the frequency of occurrence of each cause such that the THORs are satisfied although at this level the distinction between human and machine is made, the safety requirements which emerge from it are still independent of the actual physical implementation. 

It is worthwhile to mention that the DLL model can be considered as defining a special purpose parallel computer. A large number of microprocessors, each controlling the logic of a single lattice site, when arranged in an architecture of a spatial, highly coordinated lattice system could constitute a machine, the size of which and consequently the size of the simulated system will be limited less by the computation time than by the cost of... 

This architectural style is used to describe both sequential and combina-. tional circuits. Hence, it is a valuable design approach for finite state machines (FSMs) or any control logic.
