Embedded High Speed ​​Buffer AD Acquisition Scheme 
Application Background Data acquisition systems are widely used in industrial measurement and control, environmental monitoring and other applications. With the development of science and technology, data acquisition technology is developing in the direction of high precision, high speed, stability, reliability, integration, and real-time systems.
Traditional data acquisition and A/D conversion products, regardless of the system volume, system power consumption, system data acquisition accuracy, and system processing capability, are not satisfactory. There is an urgent need for a lower power consumption and lower power consumption. Volume, embedded solution to achieve high-precision data acquisition, high-performance system processing capabilities. Solution Description Constant-Embedded embedded high-speed large-buffer AD acquisition system adopts ATMEL's 32-bit ARM as the system's CPU. The single chip integrates multiple functions. The periphery of the system extends the CPLD logic chip as a co-processor and extends the A/D data acquisition and conversion circuit module as well as the high-speed data acquisition buffer system FIFO, which can achieve high-precision, high-speed data acquisition; peripheral interface resources are abundant; Linux operating system has a high degree of flexibility, occupies less resources, and has high efficiency. It faces the fields of petroleum exploration, environmental monitoring, industrial control, and medical equipment. It collects and processes data and transmits network data. The real-time and logical performance is good.
