The original 8086/8088 instruction set forms the foundation of x86 architecture, which remains the backbone of modern computing.
Key Instruction Categories
The 8086 processor introduced several fundamental instruction categories:
| Category | Examples | Description |
|---|---|---|
| Data Transfer | MOV, PUSH, POP | Move data between registers and memory |
| Arithmetic | ADD, SUB, MUL, DIV | Basic mathematical operations |
| Logic | AND, OR, XOR, NOT | Bitwise logical operations |
| Control Flow | JMP, CALL, RET | Program flow control |
Legacy and Evolution
These instructions continue to be supported in modern x86-64 processors, ensuring backward compatibility across decades of software.
