Computer Architecture, Bit Manipulation & Boolean Logic

Bitwise operations form the atomic foundation of computer hardware, graphics rendering pipelines, embedded systems firmware, network protocol header parsing, and cryptographic hash algorithms. Direct bit manipulation enables developers to pack multiple boolean state flags into single integer registers, conserving memory and accelerating CPU pipeline execution.

Overview of Bitwise ALU Operations

• Bitwise AND (&): Used for masking and checking if specific flag bits are set ((status & 0x04) != 0).
• Bitwise OR (|): Used for setting specific flag bits without mutating adjacent bits (flags = flags | 0x02).
• Bitwise XOR (^): Toggles individual bit states and forms the core primitive in stream ciphers and parity checksum algorithms.
• Bit Shifts (<<, >>): Shifts bits left (multiplying by powers of 2) or right (integer division by powers of 2) across hardware registers.
