Which one is not one of the advantages of direct mapped cache against to 4-way set associative cache? A) Needs less harware to impelement B) Hit time of direct mapped would be shorter as there is only one block to which a data of physical adress can be matched C) Two squential read to 2 different addresses matching the same cache block will result in that there won't be a cache hit so the performance will drop D) It is less expensive and simplier than 4-way associative mapping E) Using direct mapped will take more advantage of spatial locality
