The software was tied to ’C40 assembly language, plus all of the specialized glue code to get four C40s to work together with the code for the particular chosen FPGA. The observation was that it had taken three years to write software for a platform that Moore’s Law made obsolete in eighteen months. Further-more, a software radio pushes most of the complexity of the radio into software, so the software development could easily become the largest, most expensive part of the system.
