使用VHDL实现三角函数的计算

The AGC is a smart programmable gain amplifier (PGA). The amplifier gain is adjusted based upon the input signal level so that the output is at a specified Target Gain. The AGC can be configured to be either a mono or stereo input / output component. For illustration purposes, the following discussion will highlight the stereo configuration.

ds1302时钟驱动程序，已在quartus上验证可以是直接使用(DS1302 clock driver, which has been verified on quartus, can be used directly)

由verilog编写的乘法器，通过两个文件的调用实现。由于子模块的调用使得程序简化了许多。(Prepared by the Verilog multiplier, through the realization of the two documents call. As the sub-modules to simplify the procedure call makes a lot.)

VHDL Vendingmachine source

本文档介绍了通用异步收发器（UART）VHDL 组件，它可以使用，也可以与PmodRS232或与一个板上的RS232端口。一个UART 部件被用于转换串行数据为并行数据，并且并行数据为串行数据。串行 转移到UART数据被放置在一个输出总线经过了UART将其转换成并行 信息。该总线可以被用作输入到其它逻辑门阵列中。所得到的数据可 然后再次使用UART组件被送回了串行。
