The Howdy Glossary

eC is an extension of the C programming language tailored specifically for embedded systems, real-time operating systems (RTOSs), and deeply embedded software. It introduces advanced features like multi-threading, message passing mechanisms, synchronization primitives, and fault-tolerant capabilities to enhance safety-critical applications. These features are designed to meet the particular needs of developers in these specialized fields by providing higher-level abstractions and tools that facilitate efficient system design. The code written in eC can be translated into ANSI C or run directly on specialized runtime environments offered by eSOL's products.

eC distinguishes itself through its unique capabilities that extend beyond standard C programming. It includes constructs for concurrent programming—lightweight processes known as "activations" support multi-threading, while message passing mechanisms and synchronization primitives such as semaphores and mutexes manage concurrent processes in real-time systems effectively. Fault-tolerant features like assertions and preconditions ensure application reliability, particularly important in safety-critical environments. This combination of advanced language constructs makes eC a robust choice for developers working within real-time embedded systems, enhancing both development efficiency and application reliability.

In a competitive landscape populated by languages like Ada and SPARK—which also cater to safety-critical applications—and real-time operating system tools such as FreeRTOS, RTEMS, and Zephyr OS, eC stands out with its emphasis on real-time responsiveness and fault tolerance. Offering flexibility through compatibility with standard ANSI C platforms or direct execution on specialized runtime environments from eSOL further bolsters its appeal. Its focus on high-reliability applications makes it especially suited for engineers developing real-time embedded systems where efficiency, responsiveness, and robust fault management are critical requirements.
