多重处理的设计选择:多处理器或多线程技术

The Design Dilemma:Multiprocessing Using Multiprocessors and Multithreading

现今,影响嵌入式市场的一个重要因素是,开发应用软件同样需要了解使用多重处理技术的通用处理器架构,这样才能使处理器实现更高的性能和更低的功耗。虽然多处理器和多线程技术都对嵌入式开发者提出了多重处理的复杂性问题,但对于不同的软件来说,他们在成本与复杂性方面有所不同。

The real change now affecting the embedded market is that the application software is also being asked to view the general purpose processor element using a multiprocessing paradigm so that this processor can also benefit from the promises of higher performance and low power. Although MP and MT both assert this multiprocessing complexity to the software developer, all is not equal when you inspect the costs and complexity trade off between the two.
