Multithreadingcomputercentral processing unitshave hardware support to efficiently execute multiplethreads. These are distinguished frommultiprocessingsystems (such asmulti-coresystems) in that the threads have to share the resources of a single core: the computing units, theCPU cachesand thetranslation looka...
architecture, an increase in area of 14% can buy an increase of throughput of 60% relative to a comparable single-threaded core (as measured using the EEMBC PKFLOW and OSPF benchmarks, run sequentially on a MIPS32 24KE core versus concurrently on a dual-threaded MIPS32 34K core). ...
Recently, a number of Android devices came out based on multicore architecture基于多核架构. For example, the Samsung Galaxy Tab 10.1 and Motorola Xoom tablets both use a dualcore processor双核处理器 (Cortex A9 cores). A multicore processor, unlike a single-core processor, can execute multiple ...

Navaux Feb 2010 Putting performance asymmetric cores inside the same processor can be a good alternative to obtain high performance per area, throughput and single-threaded perfo...

Use of multi-core architecture is inefficient. There is no actual concurrency. 2. One-to-One: We can deduce from the name that one user thread is mapped to one separate kernel thread. The user-level thread and the kernel-level thread have a one-to-one relationship. The many-to-one mod...
The VM core-lockingarchitecture supports better granularity of VM locks. This fine-grained locking minimizes the number of contended paths of thread execution. Fewer contended paths means that one thread's execution is less likely to impede other threads. This results in better multiprocessor (MP) ...
