Oscilloscopes include analysis tools like fast Fourier transform (FFT) and histograms, which provide alternative views of waveform data. FFTs add the frequency domain view, while histograms provide an entry into statistical analysis. Viewing data in the statistical domain can provide great insight into the underlying processes behind a waveform or set of measurements.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
