-===== Performance of MCAPI ===== +---- 
-The test method of the performance data of MCAPI is to measure the time required of doing message transactions about 1000 rounds between 2 endpoints on ARM and SHARC, and one round includes sending and receiving one message for each endpoint,​ that'​s what the MCAPI demo example does, so we'll measure the interval time by running the MCAPI demo example. For more information about the message transaction,​ please refer to [[resources/​tools-software/​linuxdsp/​docs/​linux-kernel-and-drivers/​mcapi/​mcapi_api|Multi-Core ​Communication API]].  +**BACK TO** [[resources/​tools-software/​linuxdsp/​docs/​linux-kernel-and-drivers/​mcapi/​start|Multi-Core ​Support]]

-==== Dependencies ==== +
- +
-There are many influences in measuring the MCAPI performance:​ +
-  * Different platform We'​ll test on all sc5xx boards(SC589,​ SC584, SC573)  +
-  * System load We assume that the system load should be normal, and can be ingored, we disable all logs of MCAPI(both Linux and Baremetal) +
-  * MCAPI operation mode +
-  +

-==== Result ==== +

-Below table is the interval time of 1000 rounds message transaction under different conditions:​ +
