Abstract Java has been applied widely because of its versatility, robustness, platform portability, and security. In Java, object related instructions dominate the execution speed of applications due to their complexity and time-consuming, and object model determines the implementation of object related instructions because it affects the object access. In this research, an object model is developed to provide parallel access of object fields, eliminate the indirections during object access, and target direct hardware implementation of object manipulation instructions. In the Java benchmark JVM98, the jHISC V4, an embedded processor based on the proposed object model for mobile and embedded computing, averagely achieves performance gain by 1.86 times and 0.39 times in the object manipulation operations, and 1.14 times and 0.21 times in all operations over the JOP and jHISC V3, respectively.
