Abstract

In the past, programming language are procedural, the design concept is based on the module and scope which are difficult to manage, but nowadays, the programming trend is Object-Oriented Programming (OOP), where objects are the key elements to build up application and the communications between different objects are through method invocation. A novel object-oriented processor offers an opportunity to enhance the system security, performance and provides a more effective way to manipulate OOP instead of using a software Virtual Machine. jHISC is a novel object-oriented processor which provides a natural way to map the concept of OOP into architectural level through the hardware object data structure. Our solution is to design secure hardware object data structures on a novel processor with Just-In-Time compilation for Java which then makes it possible to implement complex OO related bytecodes at hardware level and access some fields of object in parallel to improve the execution speed. It mainly targets J2ME and implements about 93% bytecodes and 83% OO related bytecodes in hardware directly.
