In this section, the filter design is used to demonstrate how to split the application into multiple AI Engines when an application exceeds the computational capacity of a single AI Engine. A finite impulse response (FIR) filter is a filter whose impulse response (or response to any finite length input) is of finite duration.
In the previous equation, N denotes the taps to be used to calculate each output. The calculation process when a 32 taps filter is used as an example is shown in the following figure. int16 complex types for data and coefficient are also used as an example.
