Direct mapped two lines
WebHere are the steps that explain the actual working of a direct-mapped cache: Use the line number field of the address in order to access a particular line of a given cache. Then, … WebA direct-mapped cache divides its storage space into units called cache lines. Depending on the size of a cache, it might hold dozens, hundreds, or even thousands of cache lines. In a direct-mapped cache, each cache line is independent of all the others and contains two important types of information: a cache data block and metadata.

Direct-mapped cache. Each cache line is 1 byte. 10-bit index, 6-bit tag. 1 cycle hit time. Oligarch: 2-way set associative cache. Each cache line is 1 word (4 bytes).
http://csg.csail.mit.edu/6.823S16/StudyMaterials/quiz1/pset2.pdf Set-associative cache is a trade-off between direct-mapped cache and fully associative cache. A set-associative cache can be imagined as a n × m matrix. The cache is divided into ‘n’ sets and each set contains ‘m’ cache lines. A memory block is first mapped onto a set and then placed into any cache line of the set.
WebWhich cache line should be evicted from the cache to make room for a new line? •Direct-mapped –no choice, must evict line selected by index •Associative caches –random: … WebAs an example, suppose our main memory consists of 16 lines with indexes 0–15, and our cache consists of 4 lines with indexes 0–3. In a fully associative cache, line 0 can be …
WebIn a direct-mapped cache, each memory address is associated with exactly one location within the cache. This is inflexible but easy to implement in hardware. The block location in the cache is determined by bits in the address. With an 8-word direct-mapped cache, the last two bits in the address specify a position within the word.

But i will explain a little more about tag bits. Here the size of a cashe line( which is always same as size of a main memmory block) is 8 bytes. which is 2 3 bytes. So you need 3 bits to represent a byte within a cashe line. jest authentication testWebQuestion: Suppose that we have a processor with two levels of cache hierarchy.

I read that the modern processors try to combine the benefit of both by using a technique called way-prediction. Where they predict the line of the given set where the hit is most likely to happen and search only in that line. jestbahis - twitter
