As noted, ’s short clip is a useful overview and ’s pointer covers the basics. For deeper study, two complementary approaches work well: follow a structured course for the theory and build a very small compiler by hand for practical understanding. ’s flex/yacc toy-compiler suggestion is the classic hands-on route; the notes below synthesize both directions.

A reliable theory reference is "Compilers: Principles, Techniques, and Tools" (Aho, Sethi, Ullman) — the Dragon Book — which explains lexical analysis, grammars, parsing (LL/LR), semantic checks, IRs, and optimization. For a more implementation-focused book, use Andrew Appel’s "Modern Compiler Implementation" or Cooper & Torczon’s "Engineering a Compiler". Jack Crenshaw’s "Let’s Build a Compiler" series offers short, practical installments that develop intuition quickly.

A practical learning sequence that produces the most insight: implement a tiny language in stages — tokenizer; recursive-descent parser for expressions; AST plus symbol table and semantic checks; a simple IR (three-address or stack-based); codegen to a small VM or emitted C; then add basic optimizations. Hand-coding lexer and parser first clarifies parsing and AST design faster than jumping immediately to generator tools. After basics work, experiment with parser generators (Bison/Yacc or ANTLR) and then try an LLVM backend to learn real-world code generation and optimization.

Prefer lecture series that include assignments and worked solutions rather than slide-only overviews. Use many tiny test programs and maintain regression tests. Keep initial language scope deliberately small (expressions, variables, conditionals, loops). That mix of formal reading and incremental, test-driven implementation yields the clearest, most durable understanding of how compilers actually work.

It REALLY depends on what you're expecting to see.
Here is a 90 second YouTube video that gives a fair explanation.

That was a good video.It is useful too.looking for a video with more details

Follow links; read.

I've seen that article before.but looking for more detailed ones .

You followed links, like

If you understand that example toy compiler, you should understand things quite deeply.
