<p>A description is given of the V60/V70, the first commercially based, general-purpose 32-bit microprocessor in Japan. Its functions include on-chip floating-point operations, a high-level-language-oriented architecture, software debugging support, and support functions to promote a high level of system reliability. Because high reliability is so important, the V60/V70 contains functional redundancy monitoring (FRM) support functions. The discussion covers the overall design considerations, architecture, implementation, hazard detection and control, and FRM functions. The V60/V70 uses a TRON real-time operating system specification.</p>
