Suppose that the following sequence of instructions is loaded into memory locations 10-16: 10: 7C0A 11: 7101 12: 7201 13: 1222 14: 2CC1 15: DC13 16: 0000 and you set the PC to 10 a... Suppose that the following sequence of instructions is loaded into memory locations 10-16: 10: 7C0A 11: 7101 12: 7201 13: 1222 14: 2CC1 15: DC13 16: 0000 and you set the PC to 10 and press RUN. Give the decimal number represented by the contents of R[2] when the machine halts.
Understand the Problem
The question is asking to analyze a series of machine instructions and determine the final value stored in register R[2] when the instruction sequence completes execution. This will involve understanding the instructions given and computing the resulting value in R[2].
Answer
4
The decimal number represented by the contents of R[2] is 4.
Answer for screen readers
The decimal number represented by the contents of R[2] is 4.
More Information
Executing the series of instructions from memory locations 10 to 16, the content of register R[2] results in the decimal number 4 when the sequence halts, based on the operations given.
Tips
One common mistake is not properly decoding the machine language instructions into operations. Ensure each instruction is translated and executed properly.
