TNKernel is a compact and very fast real-time kernel for the embedded 32/16 bits microprocessors. TNKernel performs a preemptive priority-based scheduling and a round-robin scheduling for the tasks with identical priority. The current version of TNKernel includes semaphores, mutexes, data queues, event flags and fixed-sized memory pools. The system functions calls in the interrupts are supported. TNKernel is a fully portable (is written mostly in ANSI C except the processor-specific parts), but the current version of TNKernel has been ported for the ARM and PIC24/dsPIC microprocessors only. TNKernel has been written "under the significant influence" of the μITRON 4.0 Specifications ¹⁾.

TNKernel support the following RTOS objects:

• tasks
• semaphores
• mutexes
• data queues
• event flags
• fixed-sized memory pools

TNKernel is a fully portable (written mostly in ANSI C except processor-specific parts), so I port original version for 16-bits Microchip MCU and DSC.

TNKernel is distributed in the source code form free of charge under the FreeBSD-like
