JBits

The JBits API is a new Java based tool set, or application programming interface (API), that allows designers to write information directly to a Xilinx FPGA to carry out whatever customer logic operations were designed for it.  The JBits API permits the FPGA bitstream to be modified quickly, allowing for fast reconfiguration of the FPGA.  With Virtex FPGAs, the JBits API can partially or fully reconfigure the internal logic of the hardware device. 

The Virtex architecture allows this reconfiguration to be as extensive as necessary and still maintain timing information.  The JBits API also makes it possible to integrate the operations of the FPGA with other system components such as an embedded processor, a graphics coprocessor, or any digital peripheral device.

JBits applications, or "applets," can use the Java API for Boundary-Scan (unveiled by Xilinx in 
September) for platform independent device configurations deployed locally or remotely over the 
Internet.  These applets can be control programs, consumer interface programs, or updates. 
Previously, Java applets were only used to send software updates via the Internet.  The JBits API  now makes its possible to create Java logic applets that can be used to send new hardware updates via the Internet.  JBits will be available over the web in 1Q99.
