Introduction to Assembly Programming with ARM

Explore arithmetic in arm assembly, including add, subtract, and multiply, and learn to use arithmetic with flags to set the CPC register and interpret negative, zero, carry, and overflow.

Explore ARM logical operations, including and, or, exclusive or, and move negative, with practical examples of bitwise operations on registers and clearing specific bits.

Explore logical shifts and rotations at the binary level, learn how left shifts double values and right shifts halve them, and discover their uses in ARM, hashing, crypto, and graphics.

Explore how logical shifts and rotations operate in ARM assembly, including left/right shifts, multiplying or dividing by two, variable shift amounts, and combined move-and-shift instructions.

Explain how ARM assembly implements conditionals by translating high-level if statements into comparisons and branches, using scmp, bgt, labels, and default paths within sequential flow.

Explore how ARM assembly implements loops with branches, using LDR to load a list, summing values until the end sentinel, leveraging constants and conditional branches.

Explore the fundamentals of conditional instructions in Arm, where comparisons set flags and conditional add, move, subtract, and multiply execute only when the condition is met, reducing branches.

Learn how arm assembly uses a return address and the link register to call a function and return to the caller, via branch with link and bx lr.

Preserve and restore register values across function calls by pushing to and popping from the stack, ensuring accurate calculations and return values in Arm assembly.

Interact with hardware devices using the arm processor and the D1 SoC emulator to read switches and drive leds, explaining address constants, ldr, str, and binary values.
