dissipation [9]. In consumer technologies, multi-core is usually the term used to describe two or more CPUs working together on the same chip.Also called multicore technology, it is a type of architecture where a single physical processor contains the core logic of two or more processors. In a 2009 report, Dr Jun Ni showed that if a single core is close to being memory-bandwidth limited, then going to dual-core might give 30% to 70% improvement; if memory bandwidth is not a problem, then a 90% improvement can be expected; however, The trend in processor development has been towards an ever-increasing number of cores, as processors with hundreds or even thousands of cores become theoretically possible.Chips designed from the outset for a large number of cores (rather than having evolved from single core designs) are sometimes referred to as The composition and balance of the cores in multi-core architecture show great variety. 2 0 obj The telecommunications market had been one of the first that needed a new design of parallel datapath packet processing because there was a very quick adoption of these multiple-core processors for the datapath and the control plane. endobj These processors are packaged into a single integrated circuit (IC).These single integrated circuits are called a die. As multi-core processor-based systems enter the 3.
Some architectures use one core design repeated consistently ("homogeneous"), while others use a mixture of different cores, each optimized for a different, "How multiple cores are implemented and integrated significantly affects both the developer's programming skills and the consumer's expectations of apps and interactivity versus the device.The article "CPU designers debate multi-core future" by Rick Merritt, EE Times 2008,Chuck Moore [...] suggested computers should be like cellphones, using a variety of specialty cores to run modular software scheduled by a high-level applications programming interface.
%���� Multi-core processors are widely used across many application domains, including The improvement in performance gained by the use of a multi-core processor depends very much on the While manufacturing technology improves, reducing the size of individual gates, physical limits of Several business motives drive the development of multi-core architectures. In addition, embedded software is typically developed for a specific hardware release, making issues of The research and development of multicore processors often compares many options, and benchmarks are developed to help such evaluations.

Finally, raw processing power is not the only constraint on system performance.
Using the latest multi-core processors in integrated modular avionics (IMA) programs is a perfect solution for consolidating avionics applications and reducing size, weight, and power (SWaP) on next-generation platforms.

This can be a big factor in mobile devices that operate on batteries. They are also more difficult to manage thermally than lower-density single-core designs.
These MPUs are going to replaceMulti-core processing has also affected the ability of modern computational software development. As multi-core architectures begin to emerge in every area of computing, operating system scheduling that takes the peculiarities of such architectures into account will become mandatory.
