Micro Digital Announces SMX® v4.2

Costa Mesa, California, January 8, 2014 — Micro Digital is pleased to announce SMX v4.2. Significant improvements have been made to the smx multitasking kernel to add new, sophisticated features. Event groups, semaphores, exchange messaging, and block pools have been redesigned, and other areas have been enhanced to add more functionality, simpler usage, smaller size, and better safety. For details about these and other new features, please visit the SMX v4 page at Free SMX Evaluation Kits are available at

These new capabilities add to an already long list of special features of smx that distinguish it from other RTOS kernels. We have gathered all of this information into a single white paper, smx Special Features, to save engineers time when evaluating different RTOSes. Readers will be impressed by the thought and care that has gone into the design of the smx kernel; they will quickly see that all RTOSes are not alike.

“v4.2 delivers the new application-level kernel features and improvements that I promised when we announced v4.1,” said Ralph Moore, smx Architect and founder of Micro Digital. He continued, “I have spent time carefully studying alternative ways to design each section of a multitasking kernel. I have examined the benefits and consequences of various options thoroughly in order to find an optimal set of features and APIs. I considered not only functional aspects, but also how likely a user might be to make a mistake in using a particular feature. Simplicity, elegance, ease of use, and safety have been driving forces behind the new smx. I hope that engineers will find it is a pleasure to use.”

Availability and Licensing

SMX v4.2 is available now and includes full source code, 90 days of technical support, and no per-seat charges. All of Micro Digital’s software is royalty free and is sold with a 30‑day money-back guarantee. Full Evaluation Kits are available, at no charge, from

About SMX

The focus of the SMX RTOS, and the smx kernel in particular, is to increase safety, security, and reliability of embedded systems, and to offer features, tools, and support needed to ease application development so projects finish on time. This is in contrast to thin RTOS alternatives that have simplistic code, inadequate documentation, superficial debug tools, and poor support.
