Multiport memory is a memory that helps in providing more than one access port to separate processors or to separate parts of one processor. A bus can be used to achieve this kind of access.This mechanism applies to interconnected computers too. A multiport memory system uses separate buses between each ... Read More

In the time-shared common bus, there are numerous processors linked by a common direction to the memory unit in a common-bus multiprocessor system. The figure shows the organization of time-shared common buses for five processors.There is only one processor that can interact with the memory of another processor. The processor ... Read More

Shared Memory MultiprocessorsIn shared-memory multiprocessors, numerous processors are accessing one or more shared memory modules. The processors may be physically connected to the memory modules in many ways, but logically every processor is connected to every memory module.One of the major characteristics of shared memory multiprocessors is that all processors ...

A multiprocessor is a single computer that has multiple processors. It is possible that the processors in the multiprocessor system can communicate and cooperate at various levels of solving a given problem. The communications between the processors take place by sending messages from one processor to another, or by sharing ... Read More

A multiprocessor is a data processing system that can execute more than one program or more than one arithmetic operation simultaneously. It is also known as a multiprocessing system. Multiprocessor uses with more than one processor and is similar to multiprogramming that allows multiple threads to be used for a ... Read More

A virtual memory organization is a consolidation of hardware and software systems. It can make efficient utilization of memory space all the software operations are handled by the memory management software.The hardware mapping system and the memory management software together form the structure of virtual memory.When the program implementation starts, ...

The table execution of the address mapping is interpreted if the data in the address space and the memory space are each split into a collection of fixed sizes. The physical memory is broken down into sets of similar size known as blocks, which can range from 64 to 4096 ... Read More

Addresses that are used by programmers are known as virtual addresses, and the set of such addresses is known as the address space. Space or spot where the address is saved in the main memory is referred to as location or physical address and the set of such locations is ... Read More

Set associative mapping combines direct mapping with fully associative mapping by arrangement lines of a cache into sets. The sets are persistent using a direct mapping scheme. However, the lines within each set are treated as a small fully associative cache where any block that can save in the set ... Read More

In the associative mapping function, any block of main memory can probably consist of any cache block position. It breaks the main memory address into two parts - the word ID and a tag as shown in the figure. To check for a block stored in the memory, the tag ... Read More
