Article Introduction：The difference between modal instructions and non-modal instructions: Modal instructions are a group of instructions that can cancel each other. Once such instructions are executed, they will remain valid until they are canceled by other instructions in the same group. Non-modal instructions are only available in It is valid in the current block used. When the block ends, the command function is automatically canceled.

Article Introduction：In golang programming, instruction setting is a very important operation. When executing code, instruction settings can affect aspects such as program efficiency, resource utilization, and security. Therefore, mastering the methods and techniques of instruction setting is of great significance for the development and optimization of golang programs. Golang's instruction set architecture In golang, the instruction set architecture is based on RISC (reduced instruction set computer) design. This is because the RISC architecture has great advantages in terms of fewer instructions, shorter instruction length, and simpler instruction rules.

Article Introduction：In vue, a directive is a special attribute (attribute) with the "v-" prefix. The value of the directive attribute is expected to be a single JavaScript expression, and the syntax is "v-directive:parameter="expression"". Vue acts on HTML elements, and directives provide some special features. When binding directives to elements, directives will add some special behaviors to the bound target elements; therefore directives can be regarded as special HTML features.

Article Introduction：The completion of an instruction generally has two stages: instruction fetching and instruction execution. Execution process: First, according to the order specified by the program, the currently executed instructions are fetched from the internal memory and sent to the instruction register of the controller to analyze the fetched instructions; then the instructions are executed. According to the instruction analysis results, the controller Sends out a series of control potentials required to complete the operation.

Article Introduction：There are five common instruction cache mechanisms: "instruction cache", "prefetch mechanism", "branch target buffer", "instruction queue" and "instruction reordering": 1. Instruction cache. When the processor executes instructions, it will Instructions are read from the instruction cache and stored in the instruction cache; 2. Prefetch mechanism, the processor predicts the instructions that may be needed and loads these instructions into the instruction cache in advance; 3. Branch target buffer, used to store the instructions predicted by the processor The target address of the branch instruction to speed up the execution of the branch instruction, etc.
