Solve Portable Design Problems Using Convenient Concurrency: SMP multicore processors offer many advantages in portable products-if they're properly designed

摘要

Discussions of multicore chips, multiprocessors and associated programming models for portable system design continue to be narrowly hounded by a locus on individual, general-purpose processor architectures. DSPs and RTL blocks, which severely limits the possible ways in which you might use multiple computing resources to attack problems. Big semiconductor and server vendors offer symmetric multiprocessing (SMP) multicore processors, with each core supporting multiple threads. Such multicore chips are found in large servers and laptops. However, these power-hungry, general-purpose multiprocessor arrays do not serve well as processing models for many portable systems.
