| | CPU cache -- Facts, Info, and Encyclopedia article |
 | | The first hardware cache used in a computer system was not actually a data or instruction cache, but rather a TLB. | | | These predictors are caches in the sense that they store information that is costly to compute. | | | Once the address has been computed, the one cache index which might have a copy of that datum is known. |

| | Cache memory, utilized on machines such as the IBM System/360 Model 91 as early as 1968, was created to address the von Neumann bottleneck. | | | The transfer of memory from the cache to the CPU is much faster than the transfer of memory from main memory to the cache, which makes cache memory a good technique for speeding up data processing (Hayes, 1998). | | | In the event of a cache miss, a block of memory in the cache is replaced with the desired block of memory which exists in main memory (M2). |

| | Cache Memory |
| | Cache memory doesn't know anything about data structures at all, so the simple and not very useful answer to your question is that data structures are treated by the cache memory the same as everything else. | | | The cache system doesn't worry about data structures at all, but rather whether a given address in main memory is in the cache or not. | | | In general, though, cache memory works by attempting to predict which memory the processor is going to need next, and loading that memory before the processor needs it, and saving the results after the processor is done with it. |

| | Cache memory |
| | This is normally the width of the data bus between the cache memory and the main memory. | | | The way size, or degree of associativity, of a cache also has an effect on the performance of a cache; the same reference determined that, for a fixed cache size, there was a roughly constant ratio between the performance of caches with a given set associativity and direct-mapped caches, independent of cache size. | | | In the PDP-11/60, the data path from memory to cache was the same size (16 bits) as from cache to the CPU. |

| | Memory Upgrades: The Relationship Between Cache and Main Memory |
| | Operating systems and applications use cache memory to store data or instructions that the processor is working with at the time, or is predicted to work with shortly; this allows the processor to get information quickly from the faster cache memory. | | | The Level 1 (L1) cache is in the Intel Pentium processor, the Level 2 (L2) cache memory is optional and found on the motherboard of most Intel Pentium processor-based systems. | | | In this example, all the main memory installed is cacheable and thus this process of loading main memory "from the top" is typically transparent to you, the user. |

| | Cache Memory |
| | Cache memory is used to increase the performance of a computer system, as studies have shown that most programs execute the same code and access the same data in a looping fashion. | | | Cache memory is small, expensive, but fast memory that sits between the processor and main memory. | | | If the processor requests data that is not in cache memory and must be accessed from main memory, this is called a cache miss. |

| | What is cache? - A Word Definition From the Webopedia Computer Dictionary |
| | Two types of caching are commonly used in personal computers: memory caching and disk caching. | | | Memory caching is effective because most programs access the same data or instructions over and over. | | | Disk caching can dramatically improve the performance of applications, because accessing a byte of data in RAM can be thousands of times faster than accessing a byte on a hard disk. |

| | The PC Technology Guide |
| | One solution is to use "cache memory" between the main memory and the processor, and use clever electronics to ensure that the data the processor needs next is already in cache. | | | The system memory is the place where the computer holds current programs and data that are in use, and, because of the demands made by increasingly powerful software, system memory requirements have been accelerating at an alarming pace over the last few years. | | | With a large amount of memory, the difference in time between a register access and a memory access is very great, and this has resulted in extra layers of "cache" in the storage hierarchy. |

| | cache memory - a Whatis.com definition |
| | Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. | | | As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory. | | | An L1 cache is on the same chip as the microprocessor. |

| | Cache memory |
| | Cache memory allocates memory for the hash table, the FAT, the Turbo FAT, suballocation tables, the directory cache, a temporary data storage area for files and NLM files, and available memory for other functions. | | | If the cache memory uses the default block size and a file takes more than one block, the file is placed in a second noncontiguous block both in cache memory and on the volume (on the hard disks). | | | Since the file has changed, its cache buffer is different from the file on disk. |

| | The cache minimizes the number of outgoing transactions from the CPU, it sends and receives information from the system memory and passes it to the CPU so the CPU can do more of its work internally thus speeding overall pc performance. | | | This is a older type cache and is found on 386 and 486 machines. | | | -The cache memory is very important to the PC system and its speed. |

| | FAQ of Caching Mechanism |
| | Depending upon the cache restrictions on the cache item, it will be added either to the disk or to the memory cache. | | | In general, documents are stored preferentially in disk cache and not memory. | | | When the cache has been operational for a while, and the amount of available space for a new item becomes insufficient, the cache deletes approximately 10% of its size to make space for the item. |

| | Reading Cache Memory |
| | The cache controller copies areas of main memory that it thinks are going to be needed to the cache memory, which the processor can then access at high speeds. | | | That is what the cache memory is there for--to automatically increase the execution speed of your program by temporarily caching the contents of main memory. | | | If you wish to use the cache as "extra memory" for your data, this is not how the cache works, and not what it was designed for. |

| | cache - Glossary - CNET.com |
| | Caches come in many types, but they all work the same way: they store information where you can get to it fast. | | | A Web browser cache stores the pages, graphics, sounds, and URLs of online places you visit on your hard drive; that way, when you go back to the page, everything doesn't have to be downloaded all over again. | | | Of course, disk access is slower than RAM access, so there's also disk caching, which stores information you might need from your hard disk in faster RAM. |
