The Principles of Programming Languages conference, POPL 09, and its surrounding workshops is kicking off this week in Savannah, Georgia. Galwegians will be attending most of the conferences: you might be able to find Levent at VMCAI or the Twelf Tutorial, or Iavor at TLDI or POPL, and Jeff Lewis (now at Signali) will be giving a keynote at PADL. Step up and say “hello!”.
Signali Corp is the latest technology commercialization spinout from Galois, chartered with commercialization of hardware IP core design technology aimed at the FPGA and ASIC markets. Engineers at Galois and Signali have used the proprietary technology to deliver to government prime contractors the highest performing FPGA implementations in the world for a set of common cryptographic algorithms.With this technology, Signali is well-placed to make a significant impact on the IP core market with their ability to re-tune their cores to meet the customer’s design constraints, whether speed, or power, or area. The technology is especially well suited for optimizing hardware designs of computationally complex functions such as those common in digital signal processing and cryptographic systems.Galois enlisted the experience of Brian Moore, a seasoned design engineer and lab director from Intel, to lead Signali. Moore brings over 25 years of experience in the semiconductor and energy research industries. Galois co-founder Jeff Lewis, is leading the technology development as Chief Technology Officer. Signali is currently co-located with Galois in the historic Commonwealth Building in downtown Portland, Oregon. The company is engaged with Achronix Semiconductor to develop a portfolio of very high performance IP cores for their next-generation FPGAs. Sample performance and utilization numbers for IP cores running on the Achronix Speedster FPGA can be found on the Signali website.
Don did an interview with Michael Wrinn and Aaron Tersteeg from Intel’s Multicore Software Development podcast about Haskell, multicore and parallel programming, and the use of functional programming at Galois and in industry in general. Listen to the full interview! (15 minutes).
This Galois Tech Talk, the first for 2009, was our very own Joe Hurd talking about package management for theories. You can read the slides
Interactive theorem has grown beyond toy examples in mathematics and program verification, as demonstrated by recent successes such as the Gonthier’s formal proof of the four colour theorem and Leroy’s verified compiler from a realistic subset of C into PowerPC assembly code. As the construction of large programs led to the development of software engineering techniques, there is now a need for theory engineering techniques to support these major verification efforts.In this talk I will present the OpenTheory project, which has defined a simple ‘article’ format to represent theories of higher order logic. Theories in article format can be written by one higher order logic theorem prover, compressed by a standalone tool, stored and read by a different theorem prover. Articles naturally support theory interpretations, which leads to more efficient developments of standard theories, and also provides one approach to handling difficult constructs such as monads without extending the underlying logic. Finally, the grand vision of the OpenTheory article repository is painted, with fully automatic installation and dependency resolution.
Galois has been holding weekly technical seminars for several years on topics from functional programming, formal methods, compiler and language design, to cryptography, and operating system construction, with talks by many figures from the programming language and formal methods communities. The talks are open and free.
We take pride in personally connecting with all interested partners, collaborators and potential clients. Please email us with a brief description of how you would like to be connected with Galois and we will do our best to respond within one business day.
