CSI DSP
Overview
The CSI DSP software library is a set of general-purpose signal processing functions designed for Xuantie processors. It is divided into two versions: DSP and DSP2.
The functions within the DSP library can be categorized as:
Basic Mathematical Functions
Fast Mathematical Functions
Complex Functions
Filtering Functions
Matrix Functions
Transform Functions
Motor Control Functions
Statistical Functions
Helper Functions
Interpolation Functions
Most functions within the library are available in four versions: Q7, Q15, Q31, and single-precision floating-point.
The DSP2 library is a collection of instruction-set accelerated neural network basic units. The functions in the DSP2 library can be categorized into:
Activation Functions
Convolution Functions
Fully Connected Functions
Pooling Functions
Softmax Functions
Helper Functions
Most functions within the library are available in two versions: Q7 and Q15.
Usage
To use the DSP library functions in your application, include the csi_math.h header file.
To use the DSP2 library functions in your application, include the csky_dsp2_nnfunctions.h header file.
For more detailed usage, please refer to the CSI DSP Interface Manual and the CSI NN Interface Manual.
Attention
There are currently two types of interfaces, those starting with csky_ and those starting with csi_ . Although their names are different, they provide the same functionality. It is recommended to use the interfaces starting with csi_ , as the csky_ interfaces will be removed in future versions.
