What opcode dispatch strategies are used in efficient interpreters?

Question

What techniques promote efficient opcode dispatch to make a fast interpreter? Are there some techniques that only work well on modern hardware and others that don\'t work we

Answer 1

The question is a bit vague. But, it seems you're asking about writing an interpreter.

Interpreters typically utilize traditional parsing components: lexer, parser, and abstract syntax tree (AST). This allows the designer to read and interpret valid syntax and build a tree structure of commands with associated operators, parameters, etc.

Once in AST form, the entire input is tokenized and the interpreter can begin executing by traversing the tree.

There are many options, but I've recently used ANTLR as a parser generator that can build parsers in various target languages, including C/C++ and C#.
