Abstract

In this paper we explore design techniques and constraints for enabling high-speed Java-enabled wireless devices. Since Java execution may be required for 3G devices, efficient methods of executing Java bytecode are explored. We begin by setting a historical context for DSP architectures and describe salient characteristics of classical, transitional, and modern DSP architectures. We then discuss methods of executing Java bytecode - both software and hardware - and discuss the merits of each approach. We next describe the Delft-Java engine that we designed at Delft Technical University in the Netherlands. Finally, we compare this design to other techniques and comment on ways that Sandbridge Technologies is modifying organizational characteristics to achieve power-efficient Java execution.
