0 Introduction Electric vehicles are efficient, clean, and sustainable transportation tools of the 21st century. They are also an important solution to the two prominent issues of the energy crisis and environmental pollution. The main power source for electric vehicles is the battery, which is also a key factor limiting the development of electric vehicles. … Read more
In terms of Ethernet interface connections, there are usually two solutions: one is when the terminal product has a system running, such as Android systems on chips like RK3399, Linux systems on chips like i.MX6, and RTOS systems on low-end ARM chips like STM32F107. These chips have integrated Ethernet MACs, and by adding simple PHY … Read more
1. The Concept of “Memory Alignment” Memory alignment, also known as byte alignment, is an attribute of the memory address where a data type can be stored. This attribute is essentially the memory address itself, which must conform to certain specifications. This specification states that the memory address value must be a power of 2. … Read more
