SAN FRANCISCO RTJ Computing said Tuesday (July 19) that its simpleRTJ Java Virtual Machine (JVM) now supports consumer product developers utilizing LSI Logic Corp.'s ZSP G1 family of digital signal processors (DSPs). RTJ Computing has also joined LSI's ZSP Solution Partner Program.
RTJ Computing (Perth, Australia) said it has ported its cleanroom implementation of the Java language to the G1 family of ZSP DSP processors including the ZSP200, ZSP400 and ZSPneo. The move, the company said, benefits system designers by providing better portability to different processors, simplified system development and a reduced bill of materials across a wide range of applications.
RTJ Computing, which specializes in Java consulting and programming services, said it has created a JVM run-time environment that allows Virtual Machine to execute Java byte codes directly from the ZSP 16-bit data memory. This method of byte codes execution, the company said, virtually doubles the amount of memory available to the Java application by eliminating the need to expand the byte codes to match the ZSP architecture's native 16-bit data format.
