Advantages and disadvantages of simplified instructions and complex instructions of single chip microcomputer voice chip

Advantages and disadvantages of single chip microcomputer voice chip to simplify instructions
Advantages: relatively fast execution speed, most of them are single cycle instructions, and the required storage space is relatively small. Most of them are a storage space (a storage space here refers to the ROM storage bits of single chip microcomputer or voice chip, some are 8 bits, some are 10 bits or 12 bits, etc.) to do some simple operations, generally referring to addition, subtraction and multiplication.
Disadvantages: some algorithmic models need to be simulated by software or multiple instructions, and there are relatively few addressing modes.
Advantages and disadvantages of complex instructions in single chip microcomputer voice chip
Advantages: there are many instructions, various data storage and addressing modes, the instructions themselves have a variety of operation functions, and the relative flexibility of the instructions is high.
Disadvantages: generally, there are few single cycle instructions, and most of them need multiple clock cycles to complete an instruction.
From the advantages and disadvantages described above, it can be seen that the instruction cores of the two MCU voice chips are different. Generally speaking, simplifying instructions is to delete relatively few instructions from complex instructions and use relatively more instructions to simplify. It is mainly to simplify chip circuits, reduce costs and effectively improve relative efficiency. Because the circuit is simplified and the relative instruction cycle is shorter, most of the simplified instructions and instruction frequencies are more than 1MHz; The cycle of complex instructions is relatively long, the circuit is relatively more complex, and the intermediate delay is relatively large, so the instruction cycle is long. If you want to achieve the same instruction cycle as the simplified instruction set, you need higher design requirements.
