What's the eviction rule from the ghost cache, though? Does it share an eviction queue with the Traditional cache?

- gridspy 3y agoIt is the same size as the traditional cache, but it is also a FIFO. Naturally it doesn't need to worry about tracking access, since the moment the ghost cache is "hit" the relevant memory location is loaded into the traditional cache and the ghost cache entry becomes irrelevant. So I guess that means the ghost cache could just be a queue.
