Description of CMX-TINY+ - Scaled down version of the CMX RTOS

The CMX-TINY+ Real-Time Multi-Tasking Operating System is now available for for processors families such as Freescale 68HC08, Renesas (formerly Hitachi) H8/300 & H8/300H & H8S, Atmel AVR family, Infineon (Siemens) 80C16x, Toshiba TLCS-900, Renesas 78K0/K0S, TI MSP430, STMicroelectronics ST7 & STM8S, and others. CMX-TINY+provides slightly less functionality than the CMX-RTX RTOS. It was made to fit within the small amount of onboard RAM within the silicon, being in the range of 512 bytes and up.

The RTOS implements the following features:

 
 
  • Control tasks
  • Control events
  • Control messages
  • Control resources
  • Control cyclic timers
  • Control Semaphores (version 2.00 and up only)
  • Interrupts allowed to signal tasks
  • True preemption
  • Cooperative scheduling allowed
  • EXTREMELY Small RAM/ROM size
  • Fast context switch times
  • Low interrupt latency
