10- The basic computer instructions list in Table.5.2 does not include OR instruction. It is possible to achieve OR operation through using AND complemented with DeMorgan’s law, (AC`.M[AR]`)` L =(AC+M[AR]) L Write all instructions needed to achieve an OR operations using the memory reference AND instruction. Assume the two values to be ORed are initially in 1’s complement. One value is in memory the other one is in AC . a- Write the RTL instructions for an OR in the following table; b- Repeat a assuming that the two values to be ORed are not initially in 1’s complement. The two values are stored in the memory in Addresses A1 and A2 respectively. 11- The following register transfers are to be executed in the system of Fig. 5-4. for each transfer, use the following table to specify: (1) the binary value that must be applied to the bus select inputs S2, S1, and S0; (2) the register whose LD control input must be active (if any); (3) a memory control read or write operation (if needed). a.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
