Short Content:     The traditional DSP application system design cycle divides into 2 parts: The development design and the product realize. Completes the project design and the algorithm design and the confirmation in the development design part, generally carries on the simulation with the Matlab language, when simulation result satisfaction, enters the product to realize the stage again. Will develop the design stage the algorithm realizes with C/C or the assembly language, debugs on hardware's DSP goal board. Therefore, needs ...

Short Content: Speaking of based on the digital signal processor (DSP) system, the optimized power loss is one item important, but often with difficulty realizes project objective. Now, unified frequently based on the DSP equipment formerly respectively the independent many applications, each application possibly has many working patterns. Must obtain this kind of equipment's power distribution is a very difficult matter, idle talk entire complex system. The designers need to learn that as far as possible many best information, as well as ...
