What else can I help you with?
What will happened when you request an address that is not in the cache?
When you request an address that is not in the cache, a cache miss occurs. The system will then retrieve the data from a slower storage layer, such as main memory or disk, to fulfill the request. This process typically involves additional latency, as the data must be fetched and loaded into the cache for future access. Once the data is retrieved, it may be stored in the cache for quicker access on subsequent requests.
What is cache latency?
delay to access the data in cache in context of processor's speed. Time to access the requested data in cache , at that time processor have to wait .. is called cache latency.
Can you provide an example of a cache hit and miss scenario?
A cache hit occurs when the requested data is found in the cache memory, resulting in faster access time. For example, if a web page is visited frequently, it may be stored in the cache, leading to a cache hit when accessed again. On the other hand, a cache miss happens when the data is not found in the cache, requiring the system to retrieve it from the main memory or disk, which takes longer.
Why not make cache larger?
A cache is intended to speed things up. The larger the cache, the slower it performs. If it becomes slower to access the cache than the memory itself, it defeats the purpose of having a cache.
What is full form of CACHE?
Cache is not an abbreviation. Cache comes from the French word caché, meaning "storage" or "hidden place."
How does a two-way set-associative cache improve memory access efficiency compared to other cache configurations?
A two-way set-associative cache improves memory access efficiency by allowing each cache set to store data from two different memory locations. This reduces the likelihood of cache conflicts and increases the chances of finding the requested data in the cache, leading to faster access times compared to caches with fewer associativity levels.
Cache memory enhances?
memory access time.
Which memory has the shortest access time?
cache memory
What is the disadvantage of direct mapped cache?
The primary disadvantage of direct-mapped cache is its potential for high conflict misses. In this cache organization, multiple memory addresses can map to the same cache line, leading to frequent evictions and reloading of data even if the cache is not full. This can significantly degrade performance, especially for workloads with access patterns that repeatedly access a limited set of memory addresses. Additionally, the simplicity of direct mapping limits flexibility, as it cannot leverage more sophisticated replacement policies available in set-associative or fully associative caches.
What is role of cache memory in microprocessor what are the typical cache capacities of p4 processor?
Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory.
Is the word cache a fast central processing unit?
NO, a cache is a fast-access temporary data storage area (memory)
What stores recently visited pages for rapid access?
Cache
