Diagram to show the address mapping of RAM and Cache?
consider a RAM of 64 words with a size of 16 bits.Assume that this memory have a cache memory of 8 Blocks with block size of 32 bits.Draw a diagram to show the address mapping of RAM and Cache, if 4-way set associative memory scheme is used.
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
The process of assigning memory addresses to programs is called?
memory mapping
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 is the direct mapping cache memory?
it ia html
What is memory management scheme which support the user's view of memory?
paging
What is Runtime memory mapping?
Runtime memory mapping pertains to any given geographical?æinformation that is not officially stored memory. It is quite similar to real time in that it is the here and now status. Often times it is fed from satellite.?æ
How mapping is done between cache memory and main memory?
Its simply done. By connecting many lines :p
How many memory locations can be specified by an 14 - bit address?
A 14 bit address can specify 214 or 16,384 different locations.
Three cache mapping techniques?
Three types of mapping procedures are there? (1) Associative Mapping-The fastest and most flexible cache organizations uses associative mapping. The associative memory stores both the address and content of memory word. This permits any location in catche to store word in main memory. (2) Direct Mapping-Associative memories are expesive compared to RAM's because of added logic associated with each cell. (3) Set Associative Mapping-It is a more general method that includes pure associative and direct mapping as special case. It is an improvement over the direct mapping organization in that each word of cache can store two or more words of memory under the same index address. Each data word is stored together with its tag and the number of tag data items in one word of cache is said to form a set. With Regards Veer Thakur Chandigarh
