SW/HW co-design of a Java-based ASIP for pervasive computing in mobile applications

A 32bit Java-based ASIP (Application Specified Instruction set Processor) is designed for pervasive computing in mobile applications to run MIPS-compatible local instructions and some application-specific Java bytecodes in a RISC-like architecture. In Java-mode, some Java bytecodes employed in the specific application are decoded into local instructions by VLSI implementation. With VHDL simulation tools, SW\HW co-design verified that Java bytecodes could be executed on the processor with a local thread for a real-time visual processing. Furthermore, the design was synthesized to physical layout according to 1.2 mum standard CMOS technology and the simulation shows that the processor can run at a frequency of 20MHz.Computer Science, Hardware & ArchitectureEngineering, Electrical & ElectronicOpticsTelecommunicationsCPCI-S(ISTP)
