Support API for core#2 of custom system on chip. Release version

先进PID控制matlab仿真源程序,多个典型实例具体说明，清晰易懂。(Advanced PID control matlab simulation source code, more typical examples of specific instructions, clear and easy to understand.)

In this i attached matlab code for image retrieval function by finding the distance between training and testing features and arrange it in according to ascending order.

一个基本的小波去噪程序，可以较好的进行语音信号的噪声去除。(A basic wavelet denoising program, we can better for voice signal noise removal.)

室内环境的人体感应是物联网应用在安保、智能家居、节能环保方面的关键问题，近年来多普勒雷达体制的微波人体感应器作为一种高性能的室内人体传感器成为了一种热门的解决方案。微波人体感应器以雷达体制主动发射微波信号，探测回波中由目标人体产生的多普勒，输出触发信号。 国内外现有微波开关面临的主要问题是静止人体目标检测。本项目系统检测人体呼吸心跳微信息，拟通过长时间累积和滤波器提取微多普勒信息检测动目标。( Of the indoor environment of the human body induction is the Internet of things application in security, smart home, energy-saving environmental protection, the key problem of doppler radar system in recent years as a kind of high performance microwave sensor body interior human body sensor has become a popular solution. Body of microwave sensor to active microwave signal launch radar system, the detection by the target echo in the bodies of doppler, trigger signal output. Of the main problems in the domestic and foreign existing microwave switch target detection is still the human body. The project system to detect human breathing heartbeat micro information, through long time accumulation and filter extract micro-doppler information detection target. )
