This project features a full-hardware sound compressor using the well known algorithm: IMA ADPCM. The core acts as a slave WISHBONE device. The output is perfectly compatible with any sound player with the IMA ADPCM codec (included by default in every Windows). Includes a testbench that takes an uncompressed PCM 16 bits Mono WAV file and outputs an IMA ADPCM compressed WAV file. Compression ratio is fixed for IMA-ADPCM, being 4:1.

利用Verilog HDL语言设计了出租车计费器，使其具有时间 显示、计费以及模拟出租车启动、停止、复位等功能，并设置了动态扫描电路显示车费和对应时间，显示 了硬件描述语言Verilog—HDL设计数字逻辑电路的优越性。(Design using Verilog HDL language a taxi meter, it has time display, billing and simulation taxi start, stop, reset and other functions, and set dynamically display scanning circuit and the corresponding time fare, shows the hardware description language Verilog-HDL design advantages of digital logic circuits.)

在Quartus环境中，采用VHDL语言编写的出租车计费系统，系统共分为分频、状态切换、记程、计费等模块，模仿现实中出租车计费。-In the Quartus environment, the use of VHDL language taxi billing system, the system is divided into sub-frequency, state switching, recording process, billing and other modules, to imitate reality, taxi billing.

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.
