fpga的一个小程序用于3s500e 4*4键盘模块(fpga is a small program used 3s500e 4* 4 keyboard module)

讲述4ASK的原理并附有matlab调制解调的源码。。。。。。。。。。 注：原来上传的4ASKmod.zip不要下(The principle tells 4ASK together with modulation and demodulation matlab source. . . . . . . . . . Note: The original upload 4ASKmod.zip not down)

资源描述基于fpga的串口通信，采用verilog语言，实验开发板与pc机之间的串口通信

FIFO is a First-In-First-Out memory queue with control logic that manages  the read and write operations, generates status flags, and provides optional  handshake signals for interfacing with the user logic. It is often used to  control the flow of data between source and destination. FIFO can be  classified as synchronous or asynchronous depending on whether same clock  or different (asynchronous) clocks control the read and write operations. In  this project the objective is to design, verify and synthesize a synchronous  FIFO using binary coded read and write pointers to address the memory  array. FFIO full and empty flags are generated and passed on to source and  destination logics, respectively, to pre-empt any overflow or underflow of  data. In this way data integrity between source and destination is maintained.  The RTL description for the FIFO is
