From cache to control unit

This Hindi GATE 2026 crash course on computer organization and architecture runs to ten videos, about seventeen hours in total. It starts with CPU registers and the basics of the subject, then moves through the memory hierarchy, pipelining and the control unit.

Two halves of the course

• Memory begins with cache memory, moves through two parts on cache mapping, and covers disk and memory organization at the end.
• Processor covers pipeline processing and floating-point representation, instructions and addressing modes, and the CPU and control unit.

The input-output material sits between these halves, so it is worth reviewing as a bridge between memory and the processor.

Using the course

Cache mapping is the most calculation-heavy stretch, so keep paper and a calculator nearby. Learners who already know the basics can skip to the pipelining videos.
