In order to ensure a high hit rate when the CPU accesses, the contents of the Cacheshould be replaced by a certain algorithm. A more commonly used algorithm is the ”least recently used algorithm (LRU algorithm), it is the most recent to least visited rowseliminated. Need to set up a counter for each line, the LRU algorithm is to hit the counteris cleared, the other line counter is incremented by 1. When the line counter value dataneeds to be replaced out of line out. This is an efficient, scientific algorithms, the courseof its counter cleared some frequent call and then do not need the data were eliminated from the cache, to improve the utilization of Dell computer adapters.
In short, the transmission speed differences between devices can use the Cache as amatch to adjust the gap, or transmission channels for these devices. Display system, thehard disk and optical disk drive, and network communication, you need to use theCache. Of static RAM Cache by the complex structure, cost a lot of money, using existingtechnology in a limited area can not do much, but this source of power is also technicalprogress, there is a need there is progress!
The importance and status of the memory in your computer after the CPU, the pros and cons of their quality has an important impact on computer performance. In order to give full play to the potential of memory, memory-related parameters in the BIOS settings to be adjusted. Below for the slightly older support Intel Pentium III, Celeron II processor,Intel 815E/815EP chipset, VIA (VIA) 694X chipset and support for AMD the Thunder bird(Thunderbird) and Duron (Duron) processor, the Gateway chargerVIA KT133 / 133A chipset, introduced inthe Award BIOS 6.0 memory optimization settings. Award BIOS for the use of the olderchipset motherboard and low memory settings is relatively less, but the settingsdescribed in this article also apply.
