質問 5：
Common instruction sets of microprocessors include reduced instruction set, complex instruction set, display parallel instruction set, etc. The following statement about instruction set is correct.
A. Show that the parallel instruction set allows the processor to execute instructions in parallel according to the schedule of the compiler without increasing the complexity of the hardware. The architecture is developed from the super long instruction frame and made a lot of improvements
B. In the complex instruction set microprocessor, each instruction of the program is executed in sequence, and each operation in each instruction is also executed by the authorized management bank.
C. The super-long instruction word instruction set integrates multiple instructions into one instruction word, which effectively improves the utilization efficiency of each computing function component of the CPU and improves the performance of the program
D. The reduced instruction set reduces the number of instructions and the addressing mode, making it easier to implement, and the parallel execution of instructions is better. The compiler is more efficient.
正解：A,B,C,D

質問 6：
Linux is a general term for a class of free-to-use and free-spread UNIX-like computer operating systems.

B. Linux has a rich set of free web server software, database and web development tools
C. The graphical interface makes it extremely easy to use compared to other systems, greatly reducing the user's learning cost
D. LINUX system is an open source system, which is relatively mature and has a complete set of authority mechanisms. High security and stability
正解：C

質問 7：
ARM microprocessors have been used in various product markets such as industrial control, consumer electronics, communication systems, network systems, and wireless systems. The following description about the characteristics of the ARM architecture is wrong.
A. Use a complex instruction set. High processing efficiency
B. Supports 16-bit, 32-bit, and 64-bit instruction sets, and is well compatible with various IOT, terminal to cloud application scenarios
C. The same function and performance occupy a small chip area, low power consumption, higher integration, and more hardware CPU cores have better concurrent performance
D. Extensive use of registers. Most data operations are done in registers, and instruction execution is faster
正解：A
