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.
2月26日，老牌轴承企业斯凯孚宣布，SKF Vertevo将成为斯凯孚汽车业务在作为一家独立公司时所使用的名称。此项宣布标志着斯凯孚在推进汽车业务分拆上迈出重要一步。按照规划，斯凯孚目标在今年第四季度将SKF Vertevo在纳斯达克斯德哥尔摩证券交易所上市，但该计划仍需董事会提出分拆及上市方案并获得股东会批准。 （界面）
