The XStend Board provides additional
support circuitry that the XSA Boards can access through their prototyping
interfaces. This circuitry extends the range of applications of the XSA Boards into
these new areas:
- The pushbuttons, DIP switches, LEDs, and prototyping area are useful
for basic lab experiments.
- The stereo codec and dual-channel analog I/O circuitry are useful for
processing audio signals in combination with DSP components synthesized with XILINX's CORE
- The video decoder allows digitization of NTSC/PAL/SECAM video for image processing applications.
- The 10/100 Ethernet interface lets the XSA Board access TCP/IP and other types of networks.
- The USB 1.1 interface lets the XSA Board appear as a low-speed or
full-speed USB peripheral to a PC.
- The RS-232 interface is useful when the XSA Board needs to send
information over a low-speed serial communication link.
- The IDE interface provides the XSA Board with access to a hard disk
for data storage and retrieval.
- External modules with new functions can be added through the daughterboard connectors.
- Custom circuitry can be built in the prototyping area.
