Microarch Club

Ben Titzer joins to talk about the history and future of WebAssembly, the design and implementation of V8's TurboFan optimizing compiler, and the Virgil programming language. We also discuss bringing high-level language features to constrained hardware, the V8 team's response to the Spectre and Meltdown side-channel attacks, and how to design high performance virtual machines.

Kay Li joins to talk about custom hardware used in high-frequency trading, development workflows for FPGA and ASIC design, and why verification has become a bottleneck in the design process. We also discuss SiLogy, the startup Kay founded with Paul Kim to improve the design workflow, including their experience applying to and going through YCombinator, their initial target market, and how the platform could evolve over time.

Nathanael Huffman joins to talk about the magic of FPGAs, the role they play in domains ranging from medical imaging to data centers, and how software development principles can be applied to logic design. We also discuss how Nathanael and the team at Oxide Computer Company built a new rack-scale computer while working remotely, and what exactly happens when it powers on and boots up.
