Semifore, Inc. operates in the software development sector, delivering interface design and implementation tools for hardware and software interactions used in system-on-chip and FPGA projects. Its products aim to improve designer productivity and interoperability by enabling multi-language support and co-design capabilities without specialized interfaces, and by providing a single source specification for register behavior and address map hierarchies. The company emphasizes rapid compilation of large register sets and the ability to lint, integrate third-party IPs, and generate cohesive RTL descriptions with instantaneous change documentation and revision tracking.

Based in Palo Alto, California, Semifore serves engineers and design teams working on complex SoC and FPGA integrations, addressing needs around accurate design descriptions, interoperability, and maintainability of hardware/software interfaces. The firm positions itself within the software development and hardware interface technology space, offering a streamlined approach to specifying and managing control and register interfaces across chip designs. A recent development noted in industry coverage is the acquisition of Semifore by Arteri, reflecting a shift in ownership while the core focus on hardware/software interface technology remains central.
