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

parallel system. Parallel computing is an efficient form of information processing which emphasizes the exploitation of concurrent events in the computing process. Concurrency implies parallelism‚ simultaneity and pipelining. Parallel events may occur in multiple resources during the same time interval; simultaneous events may occur at the same time instant; and pipelined events may occur in overlapped time spans. Parallel processing demands concurrent execution of many programs in the computer. It is

month period. Due to the mathematical nature of doubling‚ this implies that within 30-50 years computers will become more intelligent than human beings. The implications of many digital electronic devices are strongly linked to Moore ’s law: processing speed‚ memory capacity‚ sensors and even the number and size of pixels in digital cameras.All of these are improving at (roughly) exponential rates as well. This has dramatically increased the usefulness of digital electronics in nearly every segment
