用fpga實現的DA轉換器，有說明和源碼，VDHL文件。 A PLD Based Delta-Sigma DAC Delta-Sigma modulation is the simple, yet powerful, technique responsible for the extraordinary performance and low cost of today s audio CD players. The simplest Delta-Sigma DAC consists of a Delta-Sigma modulator and a one bit DAC. Since, both of these components can be realized using digital circuits, it is possible to implement a low precision Delta-Sigma DAC using a PLD.

This sample provides a generic example of a PCI IDE minidriver. The sample isolates vendor-specific code from the higher-level PCI IDE bus driver, much as SCSI minidrivers isolate code from the SCSI port driver. See the Release Notes section for more information. This sample works on both x86 and Alpha platforms, and is 64-bit compliant. It builds with Microsoft® Visual C® 6.0. It does not implement Plug and Play or Power Management.

Addfilter is a command-line application which adds and removes filter drivers for a given drive or volume. It is intended to demonstrate how to insert a filter driver into the driver stack of a device. The sample illustrates how to do this by using the SetupDi APIs. The sample works on the x86 platform. It has only been tested in a 32-bit environment. Since Addfilter is not a driver, it does not deal with Plug and Play or Power Management. No INF file is needed to install this application.

The CD Audio sample allows some non-SCSI2 CD ROMs to support audio operations by intercepting the relevant audio ioctls and translating them into the command block(s) expected by the non-compliant cdroms. It supports Plug and Play and Power Management, and is 64-bit compliant. No INF file is needed to install this driver.
