Illustrative Examples and Solutions Example 1 Logic Gate Design Exercise Design a circuit using AND OR and NOT gates to implement the following Boolean expression 3 F A B C D E Solution Step 1 Break the expression into smaller subexpressions A B C D and E Step 2 Design individual circuits for each subexpression A B requires an OR gate with inputs A and B C D requires an OR gate with inputs C and D E requires a NOT gate with input E Step 3 Connect the outputs of the subcircuits to AND gates to implement the multiplication operations Connect the output of the first OR gate to one input of an AND gate Connect the output of the second OR gate to another input of the same AND gate Connect the output of the NOT gate to the third input of the AND gate Step 4 The output of this final AND gate represents the overall Boolean expression F Example 2 Memory Addressing Exercise A computer system has a 32bit address space What is the maximum amount of memory in bytes that can be addressed Solution Step 1 Understand that a 32bit address space means there are 232 distinct memory locations Step 2 Since each memory location stores one byte the maximum memory size is 232 bytes 4294967296
