Virtual Memory Computer Organization and Architecture by admin - January 12, 20230 Virtual Memory Programs developed by the software engineers are stored in the auxiliary storage, however, when executed a copy or part of the program get transferred to main memory. The CPU always refers to the main memory to access instructions or the data. If the referenced item is not found then it is transferred from auxiliary storage to the main memory. Virtual memory is a concept that permits programmers to to construct programs as though a very large memory space were available. It provides a mechanism for translating program-generated address into the physical or main memory locations. Address Space Vs Memory Space: Address used by the programmers is called virtual address and the set of such addressed is called the address space. The addresses
Cache Memory Computer Organization and Architecture by admin - January 11, 20230 Cache Memory Cache memory is the fastest component in the memory hierarchy and approaches the speed of the CPU. A cache is organized between the CPU and the main memory to speed up the operation of a computer system. Some of the examples of the type of data or programs stored in cache may include: Table look up Code of functions Code of loops Array of data Advantage of using Cache: As the access time of cache memory is less than the access time of the main memory by a factor of 5 to 10, thus reducing the total memory access time. Locality of Reference: Cache is used to store the most frequently used instructions or data. Execution of a main program is in sequential order
Associative Memory Computer Organization and Architecture by admin - January 6, 2023January 7, 20230 Associative Memory Unlike the main memory which is accessed using the contents address and in sequential method, the associative memory is accessed by contents and is also called as the content addressable memory. For writing a word in memory, unused space is found by memory and the word written their. Word is read from memory by matching the word or its part with the contents/word stored in memory. Difference between main memory and associative or content addressable memory Main Memory Associative or Content addressable memory Memory accessed by using address of contents/words Memory is accessed by matching contents with word stored in memory To store a word, we assign the address and write the word at that address To write a word, memory finds the empty space and
