ARM Exception and interrupts - SlideShare

WebThe interrupt controller arbitrates and prioritizes interrupts, and in turn, provides a serialized single signal that is then connected to the FIQ or IRQ signal of the core. Because IRQ and FIQ interrupts are not directly related to the software running on the core at any given time, they are classified as asynchronous exceptions. WebThe Process Response to an Exception o Copies the CPSR into the SPSR for the mode in which the exception is to be handled. n Saves the current mode, interrupt mask, and condition flags. o Changes the appropriate CPSR mode bits n Change to the appropriate mode o Map in the appropriate banked registers for that mode o Disable interrupts n … WebMay 2, 2024 · The Vectored Interrupt Controller (VIC) takes 32 interrupt request inputs and programmable assigns them into 3 categories, FIQ, vectored IRQ, and non-vectored IRQ.

WebFeb 15, 2024 · As shown in the video, the Cortex-M interrupt entry loads the LR link register with a special value, such as 0xFFFF’FFF9, instead the actual return address. Later, when the ISR returns (e.g., via BX LR), the hardware recognizes the special LR value as an interrupt return and restores the CPU registers saved during the interrupt entry.
