ADPCMCodec.rar - The DVI Adaptive Differential Pulse Code Modulation (ADPCM) algorithm was first described in an IMA recommendation on audio formats and conversion practices [1]. ADPCM is a transformation that encodes 16-bit audio as 4 bits (a 4:1 compression ratio). In order to achieve this level of compression, the algorithm maintains an adaptive value predictor, which uses the distance between previous samples to store the most likely value of the next sample. The difference between samples is quantized down to a new sample using an adaptive step-size. The algorithm in [1] suggests using a table to adapt this step-size to the analyzed data. ADPCM has become widely used and adapted, and a variant of the algorithm performs voice encoding on cellular phones (allowing minimal data to be sent across the wireless network and increasing throughput).,2010-05-29 15:40:10,下载44次
Checkers.rar - Checkers is one of the most commonly played games in the world, each culture has its own version of it and feels as if it originated from it, though its original implementation was Chinese. This project is interesting for several reasons including the fact that the end result is concrete and enjoyable. After working on this project for such a long time, it is truly rewarding to be able to play a round of checkers on your own implementation especially knowing that you omitted some of the rules.the project is implemented in VHDL.,2010-05-27 21:40:58,下载10次
