How To Remove Burstly Image Cache?

Why not to remove ram and replace it with bigger cache Because the cache Is faster is there a problem to ram with cache even the cache is more expensive than the ram?

• Answer:

  Whilst it is true to say that the actual cache memory chips are faster than standard memory, this is becoming less and less of an advantage as we move to double data rate ram etc. Cache just stores copied pieces of your ram Most of the advantage of cache memory is gained by having the 'right' piece of memory available, this is determined by something called a caching algorythm, so for instance if you were reading a book you'd expect to read the following page next, when reading a computer program you'd expect to read the following memory next. A good caching algorythm would have that area of memory available. As the cache size grows ever larger the algorythms and indexing required become more and more complicated, thus taking longer to process, and ultimately they get so complicated that there is no gain in performance. The cache size is chosen for best performance, just making it bigger could in fact give poorer performance.
