Beginner Topic 14 of 51 Computer Architecture & Logic
Registers
Small fast storage locations inside the processor.
How it works
A register is a group of flip-flops sharing a clock that holds a word, such as the program counter or accumulator. Reading is nearly instantaneous compared with memory.
Where it is used
CPU working storage, pipeline stage boundaries.
Common pitfall
Too few registers force spills to memory, which is slower.
Where it fits in the course
Registers is topic 14 of 51 in Computer Architecture & Logic, rated Beginner. It follows Flip-Flops. The next topic is Clock Signal.
