Three-Speed Logic

Three-Speed Logic is a privately held consultancy based in Victoria, British Columbia, Canada. The firm describes itself as a whole-system design house that builds and maintains high-performance, technically demanding embedded systems for research and industrial clients. Its work spans digital and mixed-signal hardware development, custom VHDL peripherals, custom and open-source bootloaders, embedded Linux, system-wide scripting in Python, and high-level control using standard web protocols. The company is best known for its contributions to experimental cosmology. According to its own materials, Three-Speed Logic has collaborated with one of Canada's premiere experimental cosmology labs in McGill University's Physics department, and has contributed design material to a series of major instruments: the South Pole Telescope, including three generations of readout designs; the CHIME experiment, an interferometer aimed at tracing the 21 cm hydrogen line to probe the growth of the universe; the E and B Experiment (EBEX), a stratospheric balloon that flew 35 km over Antarctica in December 2012–January 2013; the POLARBEAR, POLARBEAR2, and Simons Observatory experiments; and the LiteBIRD experiment, a satellite-based cosmic microwave background telescope planned for the Earth-Moon-Sun L2 point. The firm highlights that software and hardware written by its staff has operated at the South Pole Telescope and flown at an altitude of 35 km (117,000 ft) on a stratospheric balloon experiment. It frames its ambition with the remark that it has not yet made it into space, but is working on it. Three-Speed Logic operates as a small, privately held consultancy rather than a product manufacturer, selling engineering expertise and design services. Its public contact point is Graeme Smecher. The company maintains a website at threespeedlogic.com and presents itself as proudly Canadian, based in Victoria, BC.

Three-Speed Logic is a privately held consultancy based in Victoria, British Columbia, Canada. Public information about the firm is limited, but its own website and about page describe a small engineering practice focused on embedded systems and instrumentation for demanding scientific applications. The company states that it collaborates with a number of clients, including one of Canada's premiere experimental cosmology labs in McGill University's Physics department. Through that and other collaborations, Three-Speed Logic contributed design material to several major cosmology experiments. Its readout designs were used across three generations of the South Pole Telescope. It also contributed to the CHIME experiment, described as a revolutionary new interferometer aimed at tracing the 21 cm hydrogen line back in time to probe the growth of the universe. Three-Speed Logic's hardware and software have operated in extreme environments. The firm notes that software and hardware written by its staff has operated at the South Pole Telescope and flown at an altitude of 35 km (117,000 ft) on a stratospheric balloon experiment. Its about page identifies that balloon as the E and B Experiment (EBEX), which flew 35 km over Antarctica in December 2012–January 2013. The company also contributed to the POLARBEAR, POLARBEAR2, and Simons Observatory experiments, and to the LiteBIRD experiment, a satellite-based cosmic microwave background telescope planned to launch into the Earth-Moon-Sun L2 point sometime in the mid-2020s. Beyond cosmology, Three-Speed Logic describes its general engineering practice as whole-system design. It mixes digital and mixed-signal hardware development, custom VHDL peripherals, custom and open-source bootloaders, embedded Linux, system-wide scripting using Python, and high-level control using standard web protocols. The company presents this breadth as the basis for productively building and maintaining high-performance, technically demanding systems. As of its public materials, Three-Speed Logic remains a privately held consultancy. It has not made it into space yet, as its homepage notes, but says it is working on it. The public contact for the firm is Graeme Smecher.
