Microprocessor commonly used instruction sets include simplified instruction set, complex instruction set, display parallel instruction set, etc. Which of the following statements about instruction set is correct? (Multiple choice)
A . In a complex instruction set microprocessor, each instruction of the program is executed serially in order, and each operation in each instruction is also executed serially in order
B . Simplified instruction set has simplified the number of instructions and addressing methods to make it easier to implement, the degree of parallel execution of instructions is better, and the efficiency of the compiler is higher.
C . Displaying parallel instructions allows the processor to execute instructions in parallel according to the compiled schedule without increasing hardware complexity. The architecture is developed from the ultra-long instruction set architecture and has been greatly improved.
D . Ultra-long instruction set puts 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
