@how to use

This demo show how to use ALD library drivers to accelerated calculate operation like Square root and division with signal.

At the beginning of the main program, the ald_cmu_init() function is called to initialize
the ALD library.The systic is configured as the default value"SYSTICK_INTERVAL_1MS"
(ststic interrupt occur per 1ms) in "utils.c",you can change the value in
application.To use the ALD library the ald_cmu_init() function should be called
firstly,and ald_inc_tick_weak() function should be called in SysTick_Handler().

user can perform some complex calculate like division with signal and  Square root.
