Boolean algebra defines the logic of these circuits. Three core gates form the basis of all digital computation: logic gates circuits processors compilers and computers pdf

int a = 5, b = 7; int c = a + b;

An instruction is a binary word. Example (simplified 8-bit ISA): [ 4-bit opcode | 2-bit dest reg | 2-bit src reg ] = / \ x + / \ a

These take a binary code as an input and activate a single, specific output line corresponding to that binary value. Sequential Logic Circuits

Act as digital data selectors. A MUX routes one of several data inputs to a single output line based on control signals. Decoders: Take a binary code of inputs and activate one unique output out of 2n2 to the n-th power Example (simplified 8-bit ISA): [ 4-bit opcode |

A collection of flip-flops used to store data, such as the Program Counter (PC) or instruction registers. 3. Processors: The Brain of the Computer

A crystal oscillator that generates a continuous pulse. This pulse synchronizes sequential circuits, dictating when flip-flops update their states. 3. The Processor (CPU): The Brain of the Machine

Breaks down the raw source code text into meaningful units called tokens (keywords, variable names, operators).

. This machine code is a series of binary instructions (1s and 0s) that tell the processor exactly which operations to perform. 2. The Engine: Processors Central Processing Unit (CPU)
