For each instruction below assume initially (PC) = 0x0002AE, (SR) = 0x0002, (w0) = 0x, (w1) = 0x080A, (w15) = 0x080A, and the contents of the 8 sequential bytes in data memory beginning at 0x0806 are 0x01, 0x23, 0x45, 0x67, 0x89, 0xAB, 0xCD, and 0xEF. Give the contents of any registers which have changed after each of the following instructions executes: a) mov 0x080C, w0.
b) sub w1, w0, w0.
c) mov [w15++], [--w1].
d) cp0 w0 (e) bra Z, 0x0002b4.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
