Part 3: Matrix-matrix multiplication. Neon, SVE, and ... - Arm …
2024年8月6日 · SME2 provides new instructions to perform matrix arithmetic. For example, the fmopa instruction calculates outer products. SME2 provides a multi-vector 2D predication mechanism to ensure that matrix bounds are not exceeded. Streaming SVE mode, entered using the smstart instruction, enables the SME2 instructions as well as the ZA storage.

ARM SME 简介 - 知乎
2024年1月20日 · ARMv9 引入了 SME (Scalable Matrix Extension)。 SME 是基于 SVE2 定义的。 在 SVE 基础的 向量寄存器 (Z registers) 和 谓词寄存器 (P registers) 之上,SME 新增了一个 2D 累加器 (ZA accumulator)。 这个累加器会被划分为 virtual tiles,virtual tiles 的数量和大小取决于元素的大小。 PPT 中以 32-bit 位宽的元素举了个例子。 当 SVL = 512 bit 时,一个向量寄存器 (Z register) 可以容纳 16 个 32-bit 元素。 此时,累加器会被划分为 2x2=4 个 tiles。
