实现了四bit计数器的功能，使用的是VHDL语言描述(Four-bit counter, using the VHDL language description)

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
