About this course

Computer Organisation & Architecture carries roughly 7-9 marks in every GATE CS paper, and almost all of it arrives as arithmetic: cycles for n instructions through a stalled pipeline, average memory access time across two cache levels, tag and index widths for a given configuration, disk access time from geometry.

This course is built around that fact. Fifteen topics walk the machine from instruction encoding through the datapath, control unit, pipeline and its hazards, cache organisation and performance, main memory, address translation, secondary storage, interrupts and DMA — and the final topic compares look-alike designs and shows how to choose between them.

Every lesson carries audio narration, so you can revise a topic without reading it.
