A SW/HW Interface API for Java/FPGA Co-Designed Applets

A SW/HW interface API for Java/FPGA co-designed applets is presented in this paper. The co-designed applets consists of Java software part and FPGA hardware part. With the developed virtual SW/HW interface API, software part of the applets can transparently utilize FPGAs to implement some of their computationally intensive algoritjms in a networked environment. A demonstrator of web MPEG-1 player had been constructed for this API.
