IIR(Infinite Impulse Response)
Infinite impulse response filter
IIR (Infinite Impulse Response)--Infinite impulse response, relative to FIR (Finite Impulse Response). Digital filters that can be applied to audio.
IIR filters are often used in old-fashioned audio effects and speakers because of simple hardware implementation and high efficiency. However, with the development of technology, people have made deeper progress in exploring the "distortion" of music, and people are more and more intolerant that will bring huge phase distortion IIR. Designability and phase accuracy are better FIR filters gradually replace IIR, and VIR will replace FIR.
Interrupt flag register
IIR (Interrupt Identification Register)--Interrupt Identification Register. One of the internal registers of some chips, when multiple interrupt sources coexist, it is necessary to query the IIR to understand the nature of the interrupt source.
