This document discusses Veriloggen, a Python framework for generating Verilog HDL code from Python. It allows designing hardware at the register-transfer level using Python by mapping Python constructs to Verilog modules, always blocks, wires, and other Verilog constructs. Veriloggen includes modules for RTL generation (Core), connecting Python threads to finite state machines (Thread), and defining streaming hardware (Stream). It aims to support a "Veriloggen for DSL X" approach to create domain-specific hardware description languages in Python.

The document presents four different functions (fb1, fb2, fb3, fbcpp) for solving the FizzBuzz problem and benchmarks their performance on different sized test cases. fb3 is the fastest approach, using modulo operations and ifelse statements to vectorize the logic. The document then explores compiling fb1-fb3 to C++ using Rcpp to further improve performance, with fbcpp showing the fastest results.
A talk at Open vSwitch 2018 Fall Conference. OVN control plane scalability is critical in production. While the distributed control plane architecture is a big advantage, the distributed controller on each hypervisor became the first bottle neck for scaling. This talk is to share how we (eBay and the community) solved the problem with Incremental Processing - the idea, challenges, and performance improvement results.
This document provides an introduction to real-time systems and discusses approaches to making Linux a real-time operating system. It defines hard and soft real-time systems and explains why Linux is commonly used instead of dedicated real-time operating systems. The document then discusses two main solutions, PREEMPT_RT and Xenomai 3, which provide patches to make Linux meet timing constraints through different approaches. It also provides an overview of basic real-time concepts like scheduling algorithms, preemptive vs. non-preemptive scheduling, and interprocess communication.
