Name:Exponential moving average computation
Proto:static u64 irq_timings_ema_new(u64 value, u64 ema_old)
Type:u64
Parameter:
| Type | Parameter | Name |
|---|---|---|
| u64 | value | |
| u64 | ema_old |
| 304 | If Value for the false possibility is greater at compile time(!ema_old) Then Return value |
| 307 | diff = (value - ema_old) * The main goal of this algorithm is to predict the next interrupt* occurrence on the current CPU |
| 314 | Return ema_old + (diff >> EMA_ALPHA_SHIFT) |
