00:00 Introduction & Recap of Previous Lecture 00:26 Assembly Directives & Symbol Visibility 01:03 Using extern in C with Assembly 02:08 Register Usage Overview 02:41 R0 and Multiplication Results 03:49 R1 Register Behavior 04:42 Caller-Saved Registers (R2–R17, R28–R29) 07:45 Register Y as Pointer (R28+R29) 09:05 Callee-Saved Registers (R18–R27, R30–R31) 10:06 Pointer Registers X, Y, Z 11:27 Program Execution Flow 13:09 Sequential Execution Example 14:39 Old Architectures: Fetch & Execute 16:13 Introduction to Pipelining 17:22 Multi-Stage Pipelines 19:14 CPU Speedup: Pipelining & Clock Frequency In this lecture, Naveed UL Mustafa explains essential assembly language concepts and CPU fundamentals. Topics include proper register usage in the ATmega328P microcontroller, caller vs callee register saving conventions, pointer registers (X, Y, Z), and how instructions are executed sequentially and through pipelining. The lecture also introduces the difference between RISC and CISC processors, and explores how CPU performance can be improved through pipelining and clock frequency. Perfect for students learning computer architecture, embedded systems, or assembly programming.
