If register A contained the pattern 00000000, which of the following instructions could alter the contents of register 0? (Refer to the language description table.)

Explain the concept of throughput and techniques by which throughput is increased.

Which of the following instructions (as described in the language description table) is equivalent to requesting that register A be rotated to the left by three bits?

In which of the following locations is information most readily available for manipulation by the CPU?

What mask in register F would cause the instruction 8AAF (refer to the language description table) to put a 0 in the most significant bit of register A without disturbing the other bits?

What mask in register F would cause the instruction 7AAF (refer to the language description table) to put a 1 in the most significant bit of register A without disturbing the other bits?

Which step of the machine cycle examines the op-code of the next instruction to be executed?

Describe the machine cycle.

The following table shows a portion of a machine's memory containing a program written in the language described in the language description table. What will happen if the machine is started with its program counter containing 00?

An ARM based processor is an example of what kind of computer architecture?

Suppose the instruction B₁A5 (as described in the language description table) is stored in main memory at addresses E0 and E1. Moreover, suppose registers 0 and 1 contain the patterns FF and 75, respectively. What value will be in the CPU's program counter immediately after executing the instruction? ____________

Which of the following instructions (as described in the language description table) places 00000000 in register 5?

Which of the following instructions falls in the category of data transfer instructions?

Below is a short routine written in the machine language described in the language description table and stored in a machine's memory beginning at address 50. What must be in the memory cell at address 40 to avoid an unending loop? ________________________________________

Which of the following is not an activity performed entirely within a CPU?

The following is a routine encoded in the machine language described in the language description table. Explain (in a single sentence) what the routine does. (Explain what the entire routine does as a unit rather than reciting what each instruction does.)

Which of the following instructions will not produce the same result as the other two? (Refer to the language description table.)
