Embedded systems have increasingly abundant hardware resources, represented by the popular ARM core. Arm's core has already occupied the industry, with more than half of the consumption field. Its development momentum is still soaring and is moving towards desktop processors. The performance ratio of Embedded ARM chip is high. At present, the ARM chip of Cortex-A9 is developing towards multi-core. Future embedded operating systems are not Linux and their derivatives, such as Android and ubuntu. Because Linux supports perfection, powerful performance, and stability, it supports multiple cores. In the past, Windows CE did not support multi-core resources and paid for the version. Windows CE was currently only used for armv4 architecture, so the later architecture would not be able to utilize the hardware performance; although Windows CE 7 supports armv5 later architecture, it has very few applications and has been replaced by Linux ).
Therefore, if you want to develop in the future embedded industry, you must have in-depth access to Linux!
