MovingAverage
Each time the instruction is executed, the value of In is stored in Buf[CurIndex]. The average of CurIn-
dex + 1 numbers that start from Buf[0] is calculated and stored in Out.
When the number of instruction executions reaches BufSize, the value of Q changes to TRUE.
Each time the instruction is executed, Buf[0] to Buf[BufSize
− 1] are overwritten with the value of In in
cyclic fashion. The average of Buf[0] to Buf[BufSize
− 1] is calculated and stored in Out.
The value of CurIndex returns to 1 after it reaches BufSize and it is then incremented again. The value
of Q remains TRUE.
