In future, multicore processors with hundreds of cores will collaborate on a single chip. Then, more advanced network-on-chip (NoC) topologies will be needed than today's shared busses for dual core processors.
Multicore processors work on any modern computer hardware platform. Virtually all PCs and laptops today build in some multicore processor model. However, the true power and benefit of these processors depend onsoftware applications designed to emphasize parallelism. A parallel approach divides application...
Does a multicore processor affect battery life in mobile devices? Multicore processors can have an impact on battery life in mobile devices. While modern multicore processors are designed with power-saving features, running multiple cores simultaneously can consume more power. However, advancements in...

Simplistic approaches to ease the validation effort can negate the benefits of multicore processors by limiting applications from running in parallel across multiple cores. Even worse, they can result in special case solutions that cannot be modified or expanded without revalidating the entire system....
Sun Microsystems’ Ranger supercomputer at the Texas Advanced Computing Center has 15,744 quad-core processors, for example. The emergence and success of these massively parallel systems does not automatically extend to multicore architecture. Hill and Marty [6] recently applied Amdahl’s concepts to...
Multi-core processors represent an important new trend in computer architecture. Decreased power consumption and heat generation. Minimized wire lengths and interconnect latencies. They enable true thread-level parallelism with great energy efficiency and scalability. ...

In some situations, certain applications may actually run slower on multicore processors than on single core processors. To get the full performance out of multicore chips, their applications need to break tasks into chunks for each core to work on, i.e., parallel computing. Thus, effectively...
In explaining the plan, Saab said when Java was created in 1995, memory access and CPU instructions took about the same amount of time. Since then, the introduction of multicore processors has increased the speed of CPU instructions but made memory locality a challenge. For Java primitives, ...
