& and && can both be used as logical AND operators, representing logical conjunction (and). The entire result is true only when the results of the expressions on both sides of the operator are true; otherwise, if either side is false, the result is false. && also has a short-circuit feature, meaning that if the … Read more
Introduction: Many people believe that priority represents the order of operations, influenced by mathematics or everyday life, making them sensitive to this term. Isn’t priority just about who gets processed first? However, in C language, it is not quite the case. Priority only determines the order of association in expressions, not the order of operations! … Read more

ver0.3 Introduction In previous articles, we introduced the ARM architecture’s interrupt controller GIC, which maintains a state machine for each interrupt signal. This interrupt state machine supports four states: Inactive, Pending, Active, and Active and Pending. The GIC maintains the status of each signal through internal registers and performs state transitions under relevant trigger conditions. … Read more
ver0.2 Introduction Previously, we introduced the core content of the General Interrupt Controller (GIC), an important component in the ARM architecture. Through a series of preceding articles, we elaborated on the system architecture of GIC, core components, interrupt types, interrupt signal routing mechanisms, state machine management, interrupt priorities, and other fundamental concepts. We believe that … Read more

As British author Charles Dickens wrote at the beginning of “A Tale of Two Cities”: “It was the best of times, it was the worst of times.” This statement, if applied to the current state of the Wi-Fi market, is surprisingly similar. How so? Wi-Fi has undergone more than 20 years of iterations since its … Read more
