FPGA内嵌的BRAM资源很少，此代码为DRAM代码风格，可以极大程度上减少FPGA内嵌资源的消耗。txt文档中含源代码，直接粘成vhdl即可

用vhdl描写的通用异步改进dram控制器，经过编译器综合和仿真测试，符合设计要求。-Using VHDL descr iption Universal Asynchronous improved dram controller, through an integrated compiler and simulation testing, in line with the design requirements.

DRAM simulator implemented in verilog/VHDL

VHDL VGA彩条发射器，里面有4个文件，分别是直接输出的，还有通过ROM查找颜色的，通过RAM和DRAM的-VHDL VGA color of the transmitter, there are 4 files, namely, direct output, as well as to find color by ROM, RAM and DRAM through the
