Co Computer Organization Cache Memory Pdf Cpu Cache Computer When the cpu needs data held in virtual memory, it asks the operating system to first load it into ram, which is quick to access. less used data is moved from ram to virtual memory. When virtual addresses are used, the system designer may choose to place the cache between the processor and the mmu or between the mmu and main memory. a logical cache (virtual cache) stores data using virtual addresses. the processor accesses the cache directly, without going through the mmu. Reality: to context switch from process x to process y, os must save contents of registers and virtual memory for process x, restore contents of registers and virtual memory for process y. Virtual memory use main memory as a “cache” for secondary (disk) storage – managed jointly by cpu hardware and the operating system (os) programs share main memory (dram).

Virtual memory use main memory as a “cache” for secondary (disk) storage – managed jointly by cpu hardware and the operating system (os) programs share main memory (dram). ° problem: virtual memory requires two memory accesses! but page table is in physical memory! => 2 main memory accesses! ° observation: since there is locality in pages of data, must be locality in virtual addresses of those pages!. Cache memory: it is a small, fast memory that is inserted between the larger slower main memory and the processor. it holds the currently active segments of a program and their data. Memory hierarchy i7 has 8mb as shared 3rd level cache; 2nd level cache is per ‐core. Cache memory what is it? a small piece of memory that is on the chip why do it? cache access takes x time units, memory takes 100x units temporal locality: you probably will want to access again spatial locality: you probably will want items close by.
