虽然RISC-V矢量技术还有不完善的地方,但瑕不掩瑜,其解决了SIMD技术带来的二进制不兼容问题,使同一份代码可以跑在基于RISC-V架构的任何矢量位宽的处理器上,这意味着软件维护成本的大大降低,对其生态的建设是具有重大意义的。 而且RISC-V是开源架构,包括我们平头哥在内的众多团体和个人都将成为架构制定的参与者,相信...
基于向量指令集拓展的RISC-V的代码示例: 初始指令配置了前四个向量寄存器,用于存储64位浮点数据。最后一条指令禁用了所有向量寄存器。 前面例子,向量处理器大大减少了动态指令带宽,执行的指令数量仅为8条,而普通标量则为258条。当编译器为这样的代码序列生成向量指令,并且生成的代码大部分时间以向量模式运行时,称为代...
新的指令正在RISC-V基本向量指令集上构建。他们将根据核心RISC-V ISA的精神,添加对特定于图形的新数据类型的支持,作为分层扩展。支持向量,先验数学,像素和纹理以及Z / Frame缓冲区操作。它可以是融合的CPU-GPU ISA。lilibrary -RISC 3D组称它为RV64X (图1) ,因为指令将是64位长(32位将不足以支持一个健壮的...

此外RISC-V也有相应的向量扩展,下面是一篇非常好的科普文的中文翻译,英语好的建议看原文: 2.5、机器学习(包括但不限于)加速器中的SIMD运算 除了专用的向量处理器和通用处理器的SIMD扩展以外。目前很多神经网络加速器,也具有SIMD机制,毕竟前面已经说过了,SIMD是一种思想。一种思想,并不一定只有某一种特定的处理器可...
