LEGv8: Machine Code, Registers & Subroutines
by turhan-ergene
The machine code trips up more students than the assembly itself. Hex/binary conversion, MOVZ vs MOVK, immediate-value limits, and translating real bit patterns to assembly and back — practice built for 1DT301's labs and exam.

Study material
The hexadecimal (or base-16) numbering system uses sixteen unique symbols: digits 0–9 and letters A–F, where A represents 10, B is 11, up to F which is 15.
Why it’s important:
-- Compactness: Binary 11110000 can be written as F0 in hex.
-- Ease of conversion: Each hex digit corresponds to a fixed 4-bit binary group.
-- Applications: Memory addresses, machine code, color codes in web design (#FF0000 for red), and debugging.
Examine the table given above and sort the values in correct order.
