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.

开发系统上采用的时钟信号的频率是20MHz，可分别设计计数器对其计数，包括计秒、分、小时、日、周、月以及年等。在每一级上显示输出，这样就构成了一个电子日历和时钟的模型。为了可以随意调整计数值，还应包含设定计数初值的电路-Development system using the clock signal frequency is 20MHz, the design can be counter to its count, including seconds, minutes, hours, days, weeks, months and years. At every level to show the output, thus constitutes an electronic calendar and clock models. Can also adjust the order value, should also be included in setting the initial count circuit
