Addressing modes and instruction formats in computer architecture explained
Addressing modes and instruction formats explained: immediate, direct, indirect, indexed and PC-relative effective addresses, and 0/1/2/3-address machines.
Floating point representation: IEEE 754 format and arithmetic explained
Computers store real numbers in a fixed number of bits, so they cannot store every real number exactly. Floating point packs a huge range of magnitudes into 32 or 64 bits by trading away some precision, and IEEE 754 is the standard almost every processor follows. This topic is a dependable source of encoding and precision questions, all resting on the same field layout and normalization rule.
