A Central Processing Unit (CPU) is a massive collection of interconnected combinational and sequential circuits scaled down to a microscopic level. The processor executes instructions stored in a computer's memory. Key Components of a Processor
Outputs 1 if the inputs are different, but 0 if they are the same.
Checks the AST for logical errors, such as trying to add a text string to an integer or using a variable that hasn't been declared. A Central Processing Unit (CPU) is a massive
Flips the input. If you input 1, it outputs 0. AND Gate: Outputs 1 only if all inputs are 1. OR Gate: Outputs 1 if at least one input is 1.
: Circuits that add binary digits together to perform mathematical calculations. Checks the AST for logical errors, such as
At the lowest physical level, computers deal with electricity. We represent the presence of voltage as and the absence as 0 (False) . Logic gates are physical devices that implement Boolean algebra to manipulate these binary signals.
The Central Processing Unit (CPU) is a massive collection of circuits synchronized by a clock signal. It executes instructions (machine code) to perform computations. AND Gate: Outputs 1 only if all inputs are 1
To understand a processor, it's helpful to break it down into its main components:
