Threads with higher priority will be given a longer execution time also known as quantum or time slice than threads with a lower priority. However the kernel also knows other types of units of execution known as interrupt service routines ISRs. Devices connected to the system may interrupt on a connected CPU and cause their interrupt service routines to execute.
An interrupt can occur on the same processor that an audio program is running on. Any thread that was running on the processor on which an interrupt occurred will be temporarily halted regardless of its priority. The DPC will most likely run immediately on the same processor which means the audio application will halt until both the ISR and the DPC routines have finished execution.
If execution time gets too high, the audio program may be unable to deliver audio buffers to the hardware in a timely manner. About hard pagefaults.
Windows uses a concept of virtual memory which relies on the page translation system provided by the CPU. Whenever a memory address is requested which is not available in physical memory not resident , an INT 14 will occur. If the page in which the address resides is known to Windows but not resident, Windows will read in the required page from the page file. That is known as a hard pagefault and can take a lot of time to complete. If the page can be read in from the hard disk cache, the price will be limited.
This set of steps is used mostly to optimize Solution 3: Tampering As important as this arrangement is, it has a problem of latency at times. The cause behind high DPC latency is an issue with device drivers.
Some common symptoms of high DPC latency on your Windows PC can be stuttering video playback or inconsistent performance with your peripherals mouse, keyboard.
However, the most common symptoms are …. It is a Windows mechanism that handles the driver efficiency. It makes the system execute high-priority tasks first and the low-priority ones later, which helps to processing multiple tasks orderly and quickly. However, there is a noticeable delay to the audio and therefore makes playing along to songs impossible.
Dpc deferred procedure call is a mechanism in windows makes the system execute low-priority tasks later when the system is idle and high-priority tasks first. But despite these issues, it can be minimized so the problem is no longer noticeable. Verify that all windows updates are installed. Fixing pops, clicks, stutters, latency, and lag in audio and graphic, problem with - duration, 5, The audio latency problem windows is not a real-time operating system.
