Unformatted text preview: QUIZ 1 1.) Implement the following two functions using only a 4-input, 2-output, 4-product-term PLA and additional inverters, if required: - f(w,x,y,z) = (w + y)(x + z) - g(w,x,y,z) = (w + y)’ + (x + z)’ + xy
NOTE: Both functions are to be implemented using the one PLA . 2.) The ASM on the other screen deﬁnes an algorithm to perform multiplication of two unsigned 4-bit binary numbers. a.) Draw a logic diagram specifying the component organization of the PROCESSOR component of the sequential circuit. You may use any gates, ﬂipﬂops, registers, full-adders, etc., to represent the components. Label the size of all data buses and label all control inputs. b.)Construct the state diagram of the SEQUENCER component and from it obtain a logic diagram for an implementation using D ﬂip-ﬂops. c.) Deﬁne Boolean expressions or step-action statements that deﬁne the CONTROL POINT SE:ECTOR. ...
