Lec#23:Compare String (CMPS) instruction | Computer Organization & Assembly Language

🎥 Lec#23: Compare String (CMPS) Instruction | Computer Organization & Assembly Language (COAL) Welcome to Lecture 23 of the #COAL series! In this focused session, we dive deep into the CMPS (Compare String) instruction — a core part of string operations in 8086 Assembly Language. The CMPS instruction plays a crucial role in comparing sequences of data in memory, especially within loops, sorting algorithms, and searching operations. This lecture gives you a solid conceptual foundation and demonstrates practical CMPS usage through MASM and DEBUG with real examples. ✅ What You'll Learn: The syntax and working of CMPS and its variations (CMPSB/CMPSW) The role of SI, DI, and Direction Flag (DF) in string comparison How CMPS affects Zero Flag (ZF) for conditional logic Real-time examples of comparing strings in memory Efficient programming with REP and string-based instructions 📌 Ideal For: Students learning Assembly Language or Computer Architecture Developers working with low-level, memory-sensitive applications Anyone preparing for system-level programming interviews or exams 📢 Don’t forget to Like, Comment, and Subscribe for high-quality COAL content.
