SpeakEasy

"The SpectrumWare project applied a software-oriented wireless communications approach with distributed signal processing.

SpeakEasy was motivated in large part by the communications interoperability problems that resulted from different branches of the military services having dissimilar (non-interoperable) radio systems.

SpeakEasy had a very aggressive goal of implementing ten different radio waveforms in software on a single platform.

The designers chose the fastest DSP available at the time, the Texas Instruments TMS320C40 processor, which ran at 40 MHz.

The observation was that it had taken three years to write software for a platform that Moore’s Law made obsolete in eighteen months.
