Introduction to Cache Memory Cache memory is a 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 from a previous reading of data‚ it does not have to do the more time-consuming reading of data from larger memory. Cache memory is sometimes described in levels of closeness and accessibility to the microprocessor. An L1 cache is on the same

CACHE Memory INTRODUCTION A CPU cache is a cache used by the central processing unit (CPU) of a computer to reduce the average time to access memory. The cache is a smaller‚ faster memory which stores copies of the data from frequently used main memory locations. Most CPUs have different independent caches‚ including instruction and data caches‚ where the data cache is usually organized as a hierarchy of more cache levels (L1‚ L2 etc.) When the processor needs to read from or write to

Tutorial/Lab #4 Problems about Cache Memory 4.2 A two-way set associative cache has lines of 16 bytes and a total size of 8 bytes. The 64-Mbyte main memory is byte-addressable. Show the format of main memory address. Kb => 1‚024 Mb => 1024 * 1024 Ans. A two-way set => 2 lines / set in the cache; The cache has lines of 16 bytes and a total size of 8K bytes => There are a total of 8K bytes/16 bytes = 512 lines (23*210/24) in the cache; ‘2 lines / set in the cache’ AND ‘There are a total of

Temporal Cache Replacement Algorithm for Database Tuning Anju James‚ Nimishamol C.T. and Sheena V. M. Don Bosco College Kannur‚ India. March 24‚ 2013 Abstract Query optimization is an important area in database management system‚ especially when the database is large. Researchers have proposed several query optimization techniques for large databases. Automated physical design tuning for database systems is one of them. Most of the tools for automated tuning depend on repeated optimizing

Organization & Architecture Cache Memory 1. Introduction Computer memory is organized into a hierarchy. At the highest level (closest to the processor) are the processor registers. Next comes one or more levels of cache. When multiple levels are used‚ they are denoted L1‚ L2‚ etc… Next comes main memory‚ which is usually made out of a dynamic random-access memory (DRAM). All of these are considered internal to the computer system. The hierarchy continues with external memory‚ with the next level typically
