The Lite Evaluation/Demonstration Kit is intended to illustrate use of the AN3042. The AN3042 is compliant to the PCI 2.1 Local Bus specification. Included in the kit is a PCI add-in card, Windows drivers, demonstration applications, and documentation of the hardware and software provided. The microprocessor used on the PCI add-in card is the Motorola MPC860. The applications themselves serve as documentation on how to interface with the drivers, and also may be used to test the AN3042 on the user s prototype board.

ADPCM(Adaptive Differential Pulse Code Modulation),是一种针对 16bits( 或8bits或者更高) 声音波形数据的一种有损压缩算法,它将声音流中每次采样的 16bit 数据以 4bit 存储,所以压缩比 1:4. 而且压缩/解压缩算法非常简单,所以是一种低空间消耗,高质量高效率声音获得的好途径。保存声音的数据文件后缀名为 .AUD 的大多用ADPCM 压缩。

RS232.C was written to provide all of the basic functionality needed to employ serial I/O in any application written with Borland C language compilers. Some features are: 1. Ease of use. No assembly language or library files are used and a simple "#include" statement is all that is required to access all of the functions provided. 2. Both input and output are buffered and interrupt driven for efficiency. 3. Serial ports 1 - 4 are supported on PC, AT and PS/2 compatibles.Chained interrupts used on port 3 and 4 are allowed for so as not to interfere with devices such as a mouse or printer. Transmission speeds of 110 to 115200 baud are available. 4. Detection and utilization of hardware buffered UARTs (NS16550AF etc.) found in some machines is automatic. 5. Interrupt driven hardware and XON/XOFF flow control is provided for. 6. All source code is included. RS232.C can be used with all memory models.
