For many embedded systems USB seems to be a good solution for data acquisition
modules - as USB supports a fr a me rate of 1 ms which is fast enough for many
feedback control applications. The problem now is that USB is currently only
supported by Windows 98 and updates of Windows 95. The design of the USB host
controller again emphasizes the possibilities using USB in an embedded System:
Once the USB communication is established, the host controller can work in the
background using DMA-memory transfers - accompanied with a synchronous
interrupt every millisecond, a real time feedback control system is easily
established.
