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.

The design of the M4 iPad Air doesn't seem to have changed, as it appears to have the same LCD display Apple used in the last two iterations of the tablet. The company has stuck with the same rear-facing camera and dual-speaker setup as well.
«Это будет проявляться, например, в поставках вооружений. Сейчас мы видим, что у Украины серьезный дефицит ракет для ПВО, Patriot. Patriot поставлялись на Украину минимально, но теперь этот поток могут перекрыть полностью, потому что США нужны эти ракеты для того, чтобы хоть как-то защищать собственные базы на Ближнем Востоке от ударов иранских дронов и баллистики», — сказал политолог.
