An FIQ takes priority over an IRQ in an ARM system. Only one FIQ source at a time is supported. This helps reduce interrupt latency as the interrupt service routine can be executed directly without determining the source of the interrupt. A context save is not required for servicing an FIQ since it has its own set of banked registers.
The detection of an NMI or IRQ signal, as well as the execution of a BRK instruction, will cause the same overall sequence of events, which are, in order: [1] [3] The processor completes the current instruction and updates registers or memory as required before responding to the interrupt.
A hardware interrupt is a condition related to the state of the hardware that may be signaled by an external hardware device, e.g., an interrupt request (IRQ) line on a PC, or detected by devices embedded in processor logic (e.g., the CPU timer in IBM System/370), to communicate that the device needs attention from the operating system (OS) [7] or, if there is no OS, from the bare metal ...
BitchX / ˈ b ɪ tʃ ɛ k s / is a free IRC client [1] that has been regarded as the most popular ircII-based IRC client. [2] The initial implementation, written by "Trench" and "HappyCrappy", was a script for the IrcII chat client. [2]
An Interrupt Request Level (IRQL) is a hardware-independent means with which Windows prioritizes interrupts that come from the system's processors.On processor architectures on which Windows runs, hardware generates signals that are sent to an interrupt controller.
A software static analysis toolset for a variety of languages. Used primarily for safety critical applications in Nuclear and Aerospace industries. Moose: 2021-01-21 (7.0.3) Yes; MIT — C, C++ Java — .NET — Smalltalk Moose started as a software analysis platform with many tools to manipulate, assess or visualize software.
