Towards an Automatic Path from Java Bytecodes to Hardware Through High-Level Synthesis

1 This work has been partially supported by the Ph.D. program of the Prodep 5.2 action and the program Praxis XXI under the scope of Project PRAXIS/2/2.1/TIT/1643/95. Abstract This article describes a new approach to synthesise dedicated hardware from a system specification using the Java language. The new compiler named GALADRIEL starts from Java classfiles produced from the initial Java specification and processes the system information in order to exploit the concurrency implicit in each method, so that it can be efficiently implemented by multiple hardware and/or software components. The paper gives emphasis to the compiler techniques used to exploit the implicit concurrency and to the use of high-level synthesis to generate the hardware models from the Java bytecodes information.
