IIR滤波器种类和设计 IIR滤波器(Infinite Impulse Response Filter)是一种数字滤波器,具有无限冲激响应特性。 2023-06-20 11:31:36 FIR滤波器和IIR滤波器的区别与联系 1.根据冲激响应的不同,将数字滤波器分为有限冲激响应(FIR)滤波器和无限冲激响应(IIR)滤波器。对于FIR滤波器,冲激响应在有限时间内衰减为...
The STM32G431 has a Filter Math ACellerator (FMAC) hardware unit inside of it. This unit can take be used to implement an FIR or IIR filter without burdening the CPU. The FMAC unit has input and output circular buffers as well as a coefficient buffer. It is possible to connect the ...

Filters The most common digital filters are: • FIR (Finite Impulse Response): used, among others, in motor control and audio equalization • IIR (Infinite Impulse Response): used in smoothing data The IIR filter can be used to implement filters such as Butterwo...
For example, I hand-wrote decimating FIR filter in assembly, where all the accumulators were in single precision floating point registers (32 registers is massive number of single-cycle storage, without need of load/stores!), eliminating a lot of load and stores. With the loops unrolled, ...
