embedded systems designers using the dsPIC ? digital
signal controllers. CMX-Scheduler is specially
designed for developers whose designs do not require
a full blown RTOS and/or who are wondering if a kernel
might help their application. The perfect entry-level
kernel, CMX-Scheduler is intuitive to use and easy to

CMX-Scheduler offers many growth paths for future
designs. User applications developed with the
CMX-Scheduler kernel are upwardly compatible with
the popular CMX-Tiny+? or CMX-RTX? RTOSes.
CMX-Scheduler also is tightly integrated with the
unique CMX-MicroNet? TCP/IP stack for those

- 102 cycles (resuming a task)
? CMX functions are contained in a library, thus
reducing code size, if not referenced

applications that require networking connectivity.
CMX-Scheduler software and documentation is
delivered in electronic format and is freely licensed for
unlimited product usage on the dsPIC DSC devices.
