The aarch64 instruction set has a madd instruction that performs integer multiply-adds. Cortex A725 and older Arm cores had dedicated integer multi-cycle pipes that could handle madd along with other complex integer instructions. Cortex X925 instead breaks madd into two micro-ops, and handles it with any of its four multiply-capable integer pipes. Likely, Arm wanted to increase throughput for that instruction without the cost of implementing three register file read ports for each multiply-capable pipe. Curiously, Arm’s optimization guide refers to the fourth scheduler’s pipes as “single/multi-cycle” pipes. “Multi-cycle” is now a misnomer though, because the core’s “single-cycle” integer pipes can handle multiplies, which have two cycle latency. On Cortex X925, “multi-cycle” pipes distinguish themselves by handling special operations and being able to access FP/vector related registers.。服务器推荐是该领域的重要参考
这里多说一点：虽然现在有很多端侧的 VL 模型可以在本地 Mac 上跑起来，但它们的处理时长和并发能力实在没办法在我现有的工作流里做集成。所以我选择了一个上古的图片理解模型（Florence-2），能力是差了点，只能输出英文，但速度和并发勉强是可用的状态。
