除此之外,RISC-V V指令集制定时间较短,相比于ARM Neon等发展多年的SIMD指令集,在指令功能的丰富性上尚有欠缺,因此,在碰到一些特定场景时,需要使用更多的指令去实现相应的功能,进一步降低了整体的性能。 05小结 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...
GPU + RISC-V 目标硬件将有一个GPU功能单元和一个RISC-V核心。该组合以64位指令编码为标量指令的处理器的形式出现。关键在于编译器将从带前缀的标量操作码生成SIMD指令。其他功能包括可变问题、基于谓词的SIMD后端;分支跟踪;精确的异常;和矢量前端。设计将包括一个16位定点版本和一个32位浮点版本。前者适用于FPGA实...

Many libraries, such as OpenCV, FFmpeg, XNNPACK, and Eigen, utilize Arm or x86 SIMD Intrinsics to optimize programs for performance. With the emergence of RISC-V Vector Extensions (RVV), there is a need to migrate these performance legacy codes for RVV. Currently, the migration of NEON code...
RISC-V虽然没有添加SIMD指令集扩展,但是添加了Vector指令集扩展。 自1978年以来,IA-32指令集已从80条增加到大约1400条,主要是由SIMD推动的。因此,x86和ARM的规范和手册非常庞大。 相反,最重要的RISC-V指令的概述可以在在一张双面纸上写完。 大道至简。
