Abstract

The invention discloses a GPU (graphics processing unit) based software system architecture and a UML (unified modeling language) and ADL (architecture description language) combined describing method and belongs to the technical field of software system architectures. The GPU based software system architecture is characterized in that a pipeline and filter mode is applied to modeling, filters include a data stream preprocessing filter, a data stream relief filter, a CPU (central processing unit) loading engine filter, a GPU loading engine filter, a data stream processing filter and a visual filter, original data streams sequentially pass the data stream preprocessing filter, the data stream relief filter, the CPU loading engine filter, the GPU loading engine filter and the data stream processing filter through a pipeline, the data stream processing filter transmits data results to the GPU loading engine filter and the CPU loading engine filter in succession, and the CPU loading engine inputs the data results into the visual filter. UML and ADL are used together, advantages of the UML and the ADL are combined, and the GPU based software system architecture is better established.

Description

technical field [0001] The present invention relates to a technical field of software architecture, specifically a GPU-based software architecture and a method for combining UML and ADL. Background technique [0002] GPU (Graphic Processing Unit), the Chinese translation is "graphics processing unit". The GPU is the "heart" of the graphics card, which is equivalent to the role of the CPU in the computer. The GPU has a fairly high memory bandwidth and a large number of execution units, which can help the CPU to perform some complex calculations, reducing the graphics card's dependence on the CPU. [0003] Traditionally, the application of GPU is limited to processing graphics rendering computing tasks, which is undoubtedly a great waste of computing resources. With the continuous improvement of GPU programmability, the research on using GPU to complete general computing is gradually becoming active. Computing that uses GPUs for areas other than graphics rendering is called...
