adder

VHDL实现SPI功能源代码 -- The SPI bus is a 3 wire bus that in effect links a serial shift -- register between the "master" and the "slave". Typically both the -- master and slave have an 8 bit shift register so the combined -- register is 16 bits. When an SPI transfer takes place, the master and -- slave shift their shift registers 8 bits and thus exchange their 8 -- bit register values.-SPI realize the functional VHDL source code The SPI bus is a 3 wire bus that in effect links a serial shift register between the

外部ADC采集数据，存为数组文件。通过程序读入，然后即可求出ADC的SNR、SINAD、THD、ENOB等。(External ADC data collection, stored as an array of documents. Read through the program, then the ADC SNR, SINAD, THD, ENOB can be calculated.)
