====== FreeRTOS Addin Performance ======
The following appendix contains:
  * Performance data and code size for Analog Devices specific ports of FreeRTOS.
  * Comparison benchmark data between FreeRTOS Addin and uCOS III 

----

===== Benchmark Data =====
The benchmark data is available for the following EZ-Kits:

==== Timer Cycles ====

The following benchmarks report time and cycle count measurements for post and pending operations using varying methods of communication.

Projects below are executed to gather the benchmark data: 

  * **ISR**: calculate Interrupt service time and Time to return from an ISR when in FreeRTOS system.
  * **FLAG ISR**: calculate FLAG Post/Pend available time,context switch time when unavailable, Interrupt service time and Time to return from an ISR when in FreeRTOS system
  * **MSG ISR**: calculate Message queue Post/Pend available time,context switch time when unavailable, Interrupt service time and Time to return from an ISR when in FreeRTOS system
  * **SEM ISR**: calculate Semaphore Post/Pend available time,context switch time when unavailable, Interrupt service time and Time to return from an ISR when in FreeRTOS system
  * **MUT ISR**: calculate Mutex Post/Pend available time,context switch time when unavailable, Interrupt service time and Time to return from an ISR when in FreeRTOS system

==== Space ====
The following benchmarks report code size for several common RTOS operations within FreeRTOS. 

Projects below are executed to gather the benchmark data:

  * **NONE**:  Basic project
  * **Message** Queues: Basic project using 1 static object / Basic project using 2 static objects
  * **Flags**: Basic project using 1 static object / Basic project using 2 static objects
  * **Mutexes**: Basic project using 1 static object / Basic project using 2 static objects
  * **Semaphores**: Basic project using 1 static object / Basic project using 2 static objects
  * **ALL**: Basic project using 1 static object / Basic project using 2 static objects
