Multicore Architecture Simulation
Multicore Architecture is a major focus in modern computer architecture research. for both product development and research, multiple core processor simulation environments are necessary.A multi-core processor is a processing system composed of two or more independent cores. The cores are typically integrated onto a single integrated circuit die (known as a chip multiprocessor or CMP). A multi-core processor implements multiprocessing in a single physical package. they may implement message passing or shared memory inter-core communication methods. but may not necessarily share a single cache. cores in multi-core systems may implement architectures like superscalar, VLIW, vector processing, SIMD, or multithreading.
Advantages
The proximity of multiple CPU cores on the same die allows the cache coherency circuitry to operate at a much higher clock rate. the performance of cache snoop is improved. signals degrade less due to less travel. There will be improved response time while running CPU-intensive processes, like antivirus scans, ripping/burning media (requiring file conversion), or searching for folders.
Disadvantages
adjustments to OS and the existing software are required to maximize utilization of the computing resources. the ability of multi-core processors to increase application performance depends on the use of multiple threads within applications. Integration of a multi-core chip drives production yields down and they are more difficult to manage thermally than lower-density single-chip designs.single CPU designs may make better use of the silicon surface area than multiprocessing cores
Architecture:
The composition and balance of the cores is a topic of research. Some architectures use one core design which is repeated consistently ("homogeneous"), while others use a mixture of different cores, each optimized for a different, "heterogeneous", role .
