For a direct- mapped cache a main memory address is viewed as consisting of three fields.List and define the three fields.?
Tag Slot and Offset
What is the purpose of the direct mapped cache tag in a computer system's memory management?
The purpose of the direct mapped cache tag in a computer system's memory management is to quickly determine if a requested memory address is stored in the cache memory. This helps improve the system's performance by reducing the time it takes to access data from the main memory.
How does a direct mapped cache handle 4-word blocks?
A direct mapped cache assigns each block of memory to a specific location in the cache. With 4-word blocks, each block is stored in a specific cache line based on its memory address. This means that each block of memory can only be stored in one specific location in the cache, making it easy to determine where to look for a specific block of memory.
For a associative- mapped cache a main memory address is viewed as consisting of two fieldsList and define the two fields?
tag word
What are the differences among direct mapping associative mapping and set associative mapping?
The differences among direct mapping and set-associative mapping :Direct mapping : Each line in main memory maps onto a single cache line.Set-associative : Each line in main memory maps onto a small (collection) set of cache line.Direct mapping : A memory block is mapped into a unique cache line, depending on the memory address of the respective block.Set-associative : A memory block is mapped into any of the line of a set. The set is determined by the memory address, but the line inside the set can be any one.dont knowyet
What the difference among direct mapping associative mapping and autoassociative mapping?
Direct mappingA given Main Memory block can be mapped to one and only one Cache Memory line.It is Simple, Inexpensive, fastIt lacks mapping flexibilityAssociative mappingA block in the Main Memory can be mapped to any line in the Cache Memory available (not already occupied)It is slow, expensiveIt has mapping flexibility

What are the type of cache memory?
There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.
What is assosciative mapped cache?
An associative cache is a cache that has 1 or more extra slots for each place in memory. So if two pieces of memory map to the same place in cache, you can write both entries. In this case, you will need a cache replacement policy to determine which gets evicted first when it's full and new data arrives.
What are the two types of cache memory?
There are different type of cache memory: processor cache memory, cache memory ram,1 cache memory l2, cache memory, CPU cache memory, disk cache memory, hard disk cache, cache memory motherboard.
Can a direct mapped cache sometimes have a higher hit rate than a fully associative cache with an LRU replacement policy?
Yes. Now do your assignment yourself like everyone else.
