UCOS-II VS FreeRTOS VS CoOS VS RTX

Porting 了四種OS
當然是要比較一下的啦
不過就不比較RTX了
**新增加了 RTX Ver: 4.7

測試條件為

Task1 OS Time Wait 200mS

Task2 OS Time Wait 200mS

EXIT0 Interrupt GPIO Toggle

	RTX_4.7 (uS)	RTX_4.1.2 (uS)	FreeRTOS (uS)	UCOS-II (uS)	CoOS (uS)
Task switch Time(User API)		7.91	27.41	12.25	11.83
Task switch Time(Non API)	8.67	7.5	23.83	11.58	11.16
Interrupt Response Time(Non API)	1.83	1.91	1.83	3.16	1.91
