Interrupt Service Routines (ISR) Documentation

[felipefoz]

Hi,

I am looking for some documentation regarding ISR (interrupt service routines) in Real Time Systems.

My focus is to detect which processes can cause the CPU ISR load to rise.

I could verify that Serial Communication can be one of the issues, and DMA FIFO (FPGA - RT) also can increase that.

Does anyone have any documentation on what drives these interrupts in the LabVIEW Real Time? I couldn't find any.

Regards,
