ivthandleinterrupt is a conventional name for the central dispatch function that processes hardware interrupts in an embedded system. Its primary responsibilities include:
If ivthandleinterrupt enables interrupts during dispatch (e.g., by calling a function that enables interrupts), you risk re-entering the handler corrupting the context. Use a critical section or ensure interrupt nesting is properly managed by the hardware. ivthandleinterrupt
Usually a small piece of assembly code to handle register pushing before calling the C-based ivthandleinterrupt . ivthandleinterrupt() The "meat" of the code where the specific event is handled. IRET ivthandleinterrupt is a conventional name for the central
The IVT is a table in memory where each entry points to the start address of an interrupt handler. When a hardware interrupt occurs, the CPU: Usually a small piece of assembly code to
In a "long piece" of system code, the interrupt handling flow usually follows these stages: Description Interrupt Request (IRQ)
: Many systems allow for dynamic registration of interrupt handlers. This involves updating the IVT at runtime.
