Advantages of using an
Commercial RTOS
• Creates a professional product architecture
• Free from implementing a scheduler/related services
• Simplifies product design
• Simplifies product upgrades and maintenance
• Allows team development
• Lowers total cost of development
• Allows focus on ‘time to market’

Micrium Competitively
• An average project
with Micrium
software and tools
costs a fraction of
the industry
average.
• It is also clear that
the savings
expected when
using “free”
software does not
make it to the
bottom line.

• uC/Probe graphically visualizes the internals of any
embedded system effortlessly, with just a few mouse clicks.
• A Windows application allows you to read/write
memory of embedded target during run-time.
• Absolutely no programming – simply drag and drop
graphic components into place, and watch them go.
• Works with wide embedded processors, e.g. via
J-Link, TCP/IP, RS-232 or Proxies, etc.
• To extend capabilities of debugging software by
running both at the same time.
