摘要
在基2DC 7算法基础上,提出一种改进的后加运算策略。该策略利用循环展开技术生成的算法程序可对代码尺寸、缓存开销及读写并发性进行灵活调节,从而适应不同的运算平台结构。最后,针对该算法设计实现了参数可配置的快速算法代码生成器。
An improved post-adding method based on the Radix-2 DCT algorithm is proposed. By associating the proposed method with the loop-unrolling technique, the code size, data buffer and the concurrency of the target code can be flexibly balanced to match various processor architectures. A configurable algorithm code generator is implemented to improve the flexibility and the reusability of the algorithm.
