Computer Architecture — question 1 of 10
Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.
Imagine an L1 cache with a 1-cycle hit time and a 3% miss rate. Every miss costs an additional 100 cycles to fetch data from lower levels of the memory hierarchy. Walk me through how you'd compute the average memory access time (AMAT), and then explain in plain terms why that miss penalty dominates the average so heavily even though the miss rate is small.
This one resolves to a number. Give the value in the field below and your reasoning in the box — the number is checked exactly, by arithmetic.
