vector extensionalgorithm accelerationAs the pre-order step of convolutional neural network (CNN) computing, image preprocessing is indispensable but time-consuming. To accelerate image preprocessing, a method based on RISC-V vector extension was proposed to accelerate eleven image preprocessing algorithms ...
为应对上述难题,向量扩展(Vector Extension,RVV)作为RISC-V指令集架构的重要拓展被正式引入。RISC-V指令集架构以其开源开放特性著称,赋予了开发者在设计处理器时极大的灵活性与可扩展性,可针对不同应用场景进行定制化设计。RVV向量扩展通过引入向量指令,实现了对多个数据元素的并行处理,为提升计算性能提供了全新的途径。
