Micro Digital, Inc

Founded in 1975, Micro Digital was one of the first embedded systems firmware companies. Initially, it was an engineering company, providing hardware and firmware design services to OEMs. In 1989, Micro Digital released its realtime, multitasking kernel, smx. Over the years smx developed into the rich RTOS, SMX. Throughout its history, Micro Digital has been dedicated to providing high-quality services and developing excellent products. This has been done with our customers' needs in mind, and with emphasis on quality, support, and documentation. After focusing for many years on the functional capabilities of SMX, the priority changed to security. SecureSMX, our next generation RTOS, was the result of several years of development to solve the security problem for microcontroller-based embedded systems. It uses the Cortex-M Memory Protection Unit (MPU) to enable partitioning embedded firmware into isolated partitions so that hacker invasions are limited in scope and cannot reach vital information such as sensitive data, keys, passwords, etc, nor access code or I/O in other partitions. SecureSMX also provides limitations upon what a hacker can do from inside of a partition, thus offering a complete security solution. We offer full support for SecureSMX, including help defining partitions for new and existing products and developing secure frameworks for new designs. SecureSMX has recently been made open source and can be freely downloaded from
