IT House News on June 15th, in iPados 16, Apple brings a number of unique new features to the iPad based on M1 chip, such as the Stage Manager function used in the window. It also implemented virtual memory exchange on iOS devices for the first time. Interestingly, although Apple's memory exchange is a necessary condition for supporting the scheduling function before Taiwan, the fact is that the lowest -match iPad Air 5 does not support virtual memory exchange.

Virtual memory exchange is a function often used by computers. When the actual memory of the computer has been fully used by the system and applications, it can redefine some storage as virtual memory. MAC also supports memory exchange. Now this function is also supported for the first time in iPados 16.

According to Apple, iPados 16 allows applications to use 16GB of storage space as temporary memory. Regarding why the scheduling function in front of the stage is only provided to an iPad model with M1 chip, Apple claims that running iPad applications in the window requires super fast virtual memory exchange, which theoretically only M1 chip can be realized. Craig-Fedriciggi, director of Apple Software Engineering, said in a recent interview: "Only the iPad equipped with M1 can combine high-capacity DRAM with very high capacity and high-performance NAND to make our virtual memory Exchange speed is super fast. "Federighi emphasized that the reason why the scheduling in front of the stage was achieved because of virtual memory exchange.

But developer Steve Troughton-Smith pointed out on Twitter that the minimum matching number of iPad Air 5 does not support virtual memory exchange. This may be because the internal storage space of 64GB is not enough to swap memory. Apple also pointed out on its website that in addition to M1, the memory exchange function of iPad also requires at least 128GB of storage space.

The question now is why Apple has always said that virtual memory exchange is a necessary condition for the scheduling function in front of the stage, but the 64GB iPad Air 5 that supports the scheduling in front of the stage does not support virtual memory exchange.

IT House learned that since the release of iPados 16, many users have criticized Apple to limit the scheduling in front of the stage to the iPad using the M1 chip. Apple's public relations team quickly asked company executives to talk about how this function requires more powerful hardware in public, but some users of the previous generation iPad Pro still have skepticism about these requirements.

The front scheduling allows users to run up to eight applications at the same time on the iPad. In addition, it also supports external display, which can also be used to interact with multiple applications in the window.

The M1 chip scheduled in front of the stage requires a certain extent that it is understandable, but it seems that Apple could have worked hard to bring this feature to other iPads in some way, but they did not do so.
