说明：  In the data management system a significant role of the Data link layer is to convert the unreliable physical link between reader and tag into a reliable link. Therefore, the RFID system employs the Cyclic Redundancy Check (CRC) as an error detection scheme. In addition for reader to communicate with the multiple tags, an anti-collision technique is required. The technique is to coordinate the communication between the reader and the tags. The common deterministic anti-collision techniques are based on the Tree algorithm such as the Binary Tree and the Query Tree algorithms.

用Verilog写的基于MIPS架构的CPU，可以运行50多条指令，包括运算、分支、跳转、比较等指令，不过没有中断系统，大家可以考虑使用，我也是学校课程课设做的。。

用Verilog编写的以太网控制器，可以使用，里面是全部verilog源码(Ethernet controller based on Verilog, can be used directly, all verilog files)

it is used to compile codec
