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.
转型：人员优化与再投入就在财报公布前夕，Workday宣布将裁员约2%的员工，以使人员配置与其“最高优先级”保持一致，但这将对该季度和全年的利润率产生重大影响（包括涉及遣散费、员工福利和相关成本以及股权激励相关非现金费用等，预计1.35亿美元）。而在去年2月，Workday就宣布计划裁员8%的员工，约1600个职位。
