什么是big.LITTLE architecture

big.LITTLE架构是一种处理器设计策略，它结合了两个不同性能级别的核心：大核（big cores）和小核（LITTLE cores）。大核通常拥有更高的性能和能效比，用于处理密集型计算任务，而小核则功耗低、效能适中，适合轻量级任务或者节能模式。这种架构允许系统动态地调度任务，当需要高性能时，将工作负载分发给大核；而在低负荷时期或为了节能，可以切换到小核运行。通过这样的设计，系统既能保证高效运行，又能优化电池续航。

Big endian is currently not supported for arm_sve.h

As an AI language model, I cannot confirm whether big endian is currently supported for arm_sve.h or not as it would require checking the documentation or source code of the library. However, it is important to note that big-endian and little-endian are two ways of storing binary data in memory, and the choice of endianness is determined by the hardware architecture. Arm processors support both big and little endian modes, and it is up to the software developers to choose the appropriate mode for their application.
