When calculating a sum of products of two arrays comprising many elements (more than 256), there is a risk of exceeding the range. In this case, the obtained value is not only inaccurate but also of the opposite sign. These sudden changes of values of a signal (known as glitches) are easily recognized because they violate the characteristics of a signal.The consequences can be mitigated if the saturation logic is enabled. If, while executing current instruction, an overrun occurs, the hardware saturation logic will load the maximum positive or maximum negative value to the operating accumulator, depending on the previous value loaded to the accumulator. In this way the consequences of a range overrun are mitigated. Fig. 11-6 shows the case of an output sinusoidal signal when an overrun occured, without and with enabled saturation logic.
