We then discuss defects observed, the role of test and design to address this problem, and identify research opportunities. An example of a specification is the correct operation of the hardware of a microprocessor. While testing is important, exhaustive testing is challenging given the sheer size of modern processor designs.

Looking at sustained single-core bandwidth for a kernel composed of 100% reads, the trends for a large set of high-end AMD and Intel processors are shown in the figure below: So from 2010 to 2023, the sustainable single-core bandwidth increased by about 2x on Intel processors and about 5x on AMD processors. Details in the next blog entry.)
