ARM instruction sheets Solve for the correct CPU computations and actions. Execute these ARM instructions as if you were the ARM CPU. Write the final updated values for each memory, register and flags after the given instruction executes in the space provided. Only update the changed values. There are multiple parts of this problem. Endianness: Check for endianness in case of loads and stores, in each part of the question. If the question does not specify the endianness, you can assume little-endian. Note: Only write the changed values, if the value did not change leave the updated cell blank. Note: If the instruction causes no change in the data, clearly state why there is no change, otherwise it will be assumed you did not answer the question. For branch instructions, clearly state if the branch is taken or not taken. Q2.5 LDMIA R13!, (R10, R2, RO) Updated Data Memory Orig.
