Cache memory mapping techniques are presented. A cache may contain an index configuration register. The register may configure the locations of an upper index portion and a lower index portion of a memory addres
Mapping of main memory to a direct mapped cache Example 8.4 Cache Fields To what cache set in Figure 8.5 does the word at address 0x00000014 map? Name another address that maps to the same set. Solution The two least significant bits of the address are 00, because the address is word ...
The first method locks code and data in the cache using way addressing techniques. The second uses a set of lock bits. In the third, code and data are locked in cache using a combination of a special allocate command and reading a dedicated block of main memory. Table 12.9 lists the ...
Partitioning techniques do not prevent certain types of attacks [35]. 3. Mapping schemes are discussed in Sect. 3 and workloads in Sect. 5. 4. For small bit counts, a table lookup can be used. 5. In the original work, this scheme was applied to the shared L3 cache. 6. In our cas...
Geesh, what a waste of processing power, memory, and other system resources. After all, most of the content on your site remains the same for at least a few minutes — sometimes for days, or even weeks. So maybe you've noticed that, on average, your site does not load up as fast ...
Swapping has always been done with a one-to-one mapping of memory pages to swap slots, he said, but swapping multi-page folios breaks that assumption. He wondered if it would make sense to use filesystem techniques to track swapped-out folios.David Howells 想要在2024年Linux存储、文件系统、...
In-memory database can effectively improve the performance of database-centric applications. However, mainstream application-level caching frameworks, such as Memcached, require developers to specify what to cache while developers can hardly understand all intricate details of the application. In this pap...
One possible cause of this bug check is depletion of nonpaged pool memory. If the nonpaged pool memory is completely depleted, this error can stop the system. However, during the indexing process, if the amount of available nonpaged pool memory is very low, another kernel-mode driver requiring...
Other optimizations techniques may be possible, as you have suggested. Note: we may be able to shrink the bounding box. Currently, it's MAP_BOX_HEIGHT * MAP_BOX_WIDTH getMapBoxPoint(index) only calls one set of phi and theta at a time. ...
Optimizing JPEG on the TMS320C6211 2-Level Cache DSP 13 SPRA705 • General optimization techniques for the TMS320C6000 DSP family. There is possibility of L2 cache corruption because of the lack of coherency between L1/L2 and the external memory. The last section details all the possible ...
