Abstract

The invention discloses an execution method for a microcontroller instruction set. The execution method comprises the following steps: carrying out instruction address computation by a microcontroller, obtaining the address of an instruction, to be executed, stored in a program counter, wherein the length of the address of the instruction is fixed 16 bits; carrying out a fetch instruction by the microcontroller, and obtaining the 16-bit instruction in the address of the instruction to be executed; coding by the microcontroller, translating a binary system operation code field in the 16-bit instruction into an output signal, and indicating the function of the instruction to be executed; carrying out address computation by the microcontroller, and obtaining the operand address in the instruction to be executed; obtaining one or more operands through the operand address, carrying out function operation appointed by the instruction on the one or more operands by the microcontroller; ending when no operand is returned; carrying out computation of the operand address if operands are returned. The coding for the instruction set adopts the length of fixed 16 bits, so that the speed of the fetch instruction is improved.

Description

technical field [0001] The invention relates to a method for executing instruction operations, in particular to a method for executing instruction sets of a microcontroller. Background technique [0002] With the development of embedded technology, the microcontroller as the core of the functional control core information processing has been applied to various fields of reality. The microcontroller processes information in the form of machine instructions, so that it can directly execute various programs. Therefore, this process is actually completed by a series of machine instructions. The collection of all instructions in the microcontroller constitutes the microcontroller instruction set, which should have the characteristics of integrity, regularity, high efficiency and compatibility. In the design process of the microcontroller system, the design of the instruction set occupies a very important position, and a reasonable instruction set is very important for improving t...
