RTKernel - Real-Time Multitasking Kernel for DOS
RTKernel is a powerful real-time multitasking system. It was designed for software developers who wish to implement professional process control applications on DOS computers or embedded systems. Special care has been taken to ensure easy usage and excellent run-time performance. RTKernel is compact (about 16k code, 6k data) and provides the programmer with the basic tools needed to develop efficient real-time software.
RTKernel is a library or unit you can link to your application program. It offers a number of functions and procedures to manage tasks, semaphores, mailboxes, interrupts, etc. All RTKernel-tasks normally run within a single program. An RTKernel-application consists of a single EXE-file containing the kernel, the required drivers, and all tasks. The EXE-file can be executed on any computer running DOS. Although an RTKernel application has real-time multitasking capabilities, it is a DOS program.
