摘要
针对航空电子信息系统与通信数据链的嵌入式信息处理应用中算法软件移植性和可复用性差的问题,提出基于VSIPL标准应用编程接口的跨平台算法中间件软件设计模式,以增强多平台多系统软件可移植性及代码重用性;利用Power-VSIPL的AltiVec矢量加速、数据并行设计及循环展开,在保持原有算法处理精度基础上,提高软件运算效率1~5倍。
k method based on VSIPL API is proposed to solve the problems such as bad portability and reusabili- ty of embedded information processing in aerospace and communication field to improve portability and reusabili- ty between various systems and platforms. By AltiVee technique of Power-VSIPL, data-parallel design and loop unrolling optimization, the middleware can insure precision and increase effectiveness by 1 -5 times.
