Explain why, in MARIE, the MAR is only 12 bits wide while the AC is 16 bits wide. Hint: Consider the difference between data and addresses.

witch of the following is howZ = X - Y calculated in an ALU?  Assume unsigned integer codes.   A Z = X + 1's complement(Y) + 1   B Z = X + 2's complement(Y) + 1   C Z = X + 1's complement(Y) - 1   D Z = X + 2's complement(Y) - 1

Hello,   I am having trouble with part 1 and part 2 I was wondering if you can help me with both parts thank you

Suppose you have an LFSR with state bits (also known as the seed) (85, 84, 83, 82, 81, 80) = (1, 1, 1, 0, 1, 1) and tap bits (also known as feedback coefficients) (P5, P4, P3, P2, P1, Po) = (0, 1, 1, 1, 0, 1). What are the first 12 bits output by this LFSR? Please enter your answer in the form of unspaced binary digits (e.g. 010101010101). These come in order $08182 ... $11.
