Unformatted text preview: (c) ROM (as in Fig 6-20 in M&K) F 1( A,B,C,D ) = Σ m (0 , 1 , 2 , 3 , 6 , 9 , 11) F 2( A,B,C,D ) = Σ m (0 , 1 , 6 , 8 , 9) F 3( A,B,C,D ) = Σ m (2 , 3 , 8 , 9 , 11) Specify the input and output dimensions of your PLA,PAL and ROM. 3- Use a 32 input 6 output (32x6) ROM to convert a 6 bit binary number to its corresponding 2-digit BCD representation. Hint: Input ranges 0 to 63 so most significant bit of ten’s position is 0. 1 2 CS223 - FALL 2009 4-Design a circuit with one input x and one output z that will produce an output of 1 whenever the last four inputs are 1. Realize the circuit using D flip-flops and (a) PLA (as in Fig 6-21 in M&K) (b) PAL (as in Fig 6-23 in M&K) Specify the input and output dimensions of your PLA and PAL ....
