面向多媒体移动终端的DSP脚本语言设计

DSP Scripting Language Design for Mobile Multimedia Terminals

移动终端像移动电话等正在采用双核处理器,这种处理器包含MPU和DSP两种核心,双核处理器有利于移动终端性能的提高和功耗的降低,但它会使软件的发展更趋复杂,因为MPU和DSP都要求各自的开发程序。为了改进双核系统对软件发展的要求,研制出了一种DSP脚本语言,其运行环境可以和MPU匹配,阐述了这个系统的设计、运行和评价。

The dual-core processor is used in mobile terminals such as mobile phones. This kind of processor includes two cores, MPU and DSP. It should be noted that the dual-core processor is in favor of improving the performance of mobile terminals and lowering the power consumption. However,it makes the development of the software more complicated because MPU and DSP require their own development programs. In order to improve the requirements of software development in the dual-core system, this paper develops a DSP scripting language, the operation environment of which can match with MPU, and describes the design, operation and evaluation of this system.
