Hello Mr. Johnnie, I read "Unfortunately, the oscilloscope's hardware adds unwanted phase shift to the higher-order components of high-speed signals that can ONLY be eliminated by either significantly increasing the instrument's bandwidth, or by correcting with phase-correction DSP filtering" under the "Phase-correction Filtering" paragraph. I researched and discovered that zero-phase filters can be made (topic: ZERO-PHASE FILTERING in "Understanding digital signal processing, second edition" written by Richard G. Lyons). I simulated it in Matlab and it seems to work fine. Would you have any regards about it? Thank you for your very well written article. Marius RUSU, student at University of Birmingham.

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.
