A Karnaugh map (KM or K-map) is a diagram that can be used to simplify a Boolean algebra expression. Maurice Karnaugh introduced it in 1953 [ 1 ] [ 2 ] as a refinement of Edward W. Veitch 's 1952 Veitch chart , [ 3 ] [ 4 ] which itself was a rediscovery of Allan Marquand 's 1881 logical diagram [ 5 ] [ 6 ] (aka.
Minimizing Boolean functions by hand using the classical Karnaugh maps is a laborious, tedious, and error-prone process. It isn't suited for more than six input variables and practical only for up to four variables, while product term sharing for multiple output functions is even harder to carry out. [10]
A function of four variables has sixteen input combinations and the diagram has sixteen different squares to be filled from the truth table that defines the function. The primary difference between the Veitch and Karnaugh versions is that the Veitch diagram presents the data in the binary sequence used in the truth table while the Karnaugh map ...
Static implementations of two- and three-input C-element, [20] [21] [22] Semistatic implementations of two- and multiple-input C-element. [23] [24] [25] For a faster version see [26] In his report [3] Muller proposed to realize C-element as a majority gate with feedback. However, to avoid hazards linked with skews of internal delays, the ...
In the early days, logic design involved manipulating the truth table representations as Karnaugh maps. The Karnaugh map-based minimization of logic is guided by a set of rules on how entries in the maps can be combined. A human designer can typically only work with Karnaugh maps containing up to four to six variables.
For the case when the Boolean function is specified by a circuit (that is, we want to find an equivalent circuit of minimum size possible), the unbounded circuit minimization problem was long-conjectured to be -complete in time complexity, a result finally proved in 2008, [4] but there are effective heuristics such as Karnaugh maps and the ...
This theory can be applied to any logic system. Computer programs deal with most of this work now, but for simple examples it is quicker to do the debugging by hand. When there are many input variables (say 6 or more) it will become quite difficult to 'see' the errors on a Karnaugh map.
