A wireless data platform (10) comprises a plurality of processors (12,16). Channels of communication are set up between processors such that they may communicate information as tasks are performed. A dynamic cross compiler (80) executed on one processor compiles code into native processing code for another processor. A dynamic cross linker (82) links the compiled code for other processor. Native code may also be downloaded to the platform through use of a JAVA Bean (90) (or other language type) which encapsulates the native code. The JAVA Bean can be encrypted and digitally signed for security purposes.
