Can you help make a Boolean algebra equation or truth table of the results and simplify it with a k-map for the multiplication part please?
### Opcode Table for Logical and Arithmetic Operations Here is a detailed explanation of operations performed by various opcodes, specifically for educational purposes in digital logic design. | **Opcode** | **Operation** | **Description** | |------------|----------------------------|---------------------------------------------------------------------------------| | 000 | O = B | Output is equal to input B. | | 001 | O = A ^ B (bitwise XOR) | XOR of each bit in A with the corresponding bit in B. | | 010 | O = A AND B (bitwise AND) | AND of each bit in A with the corresponding bit in B. | | 011 | O = A OR B (bitwise OR) | OR of each bit in A with the corresponding bit in B. | | 100 | O = A + B (addition) | 8-bit addition with a final carry out bit. | | 101 | O = A - B (subtraction) | 8-bit subtraction with a borrow out bit. | | 110 | O(7) = 0, O(6:0) = B(7:1) | Logical shift of the data at input B right by one bit. | | 111 | O = A * B (multiplication) | 8-bit multiplication. Only the lower 8 bits of the result are kept, with overflow signaled. | ### Explanation of Operations: - **Bitwise Operations (XOR, AND, OR):** - Bitwise operations are performed between corresponding bits of inputs A and B, resulting in output O. - **Arithmetic Operations (Addition, Subtraction, Multiplication):** - These operations handle standard arithmetic between binary values with attention to carry and overflow. - **Logical Shift:** - The logical shift operation moves bits to the right, filling the vacant positions with zeros, effectively dividing the number by 2. This table serves as a foundation for understanding basic binary operations in digital systems.
