Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple error detecting circuits (first error detecting circuit and second error detecting circuit) into a single integrated system. The control circuit coordinates these circuits to perform different detection settings sequentially, replacing the need for multiple separate error detecting systems while maintaining comprehensive detection capabilities.

Inventive Principle:

Solution Approach 1:

The patent merges multiple error detecting circuits into one shared system. The first error detecting circuit and second error detecting circuit occupy circuit area simultaneously but are controlled to operate at different times for different settings, reducing the total area required compared to having separate dedicated systems for each setting.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The control circuit implements periodic action by alternately activating the first error detecting circuit and second error detecting circuit based on different detection settings. This time-division multiplexing approach allows comprehensive detection coverage while using a single shared circuit resource, minimizing the required circuit area.

Inventive Principle:

Solution Approach 2:

The control circuit ensures continuous useful action by seamlessly switching between the first error detecting circuit and second error detecting circuit without idle gaps. Each circuit processes detection settings in sequence, maintaining continuous error detection operation while reducing overall detection time compared to sequential processing of separate systems.

Inventive Principle:

Solution Approach 1:

The control circuit implements dynamic control by adaptively switching between the first error detecting circuit and second error detecting circuit based on the required detection setting. This dynamic allocation of circuit resources optimizes detection speed for different settings while using a single cost-effective system, rather than having fixed separate systems for each setting.

Inventive Principle:

AI summary

An error detecting system, comprising: a control circuit; and a first error detecting circuit, coupled to the control circuit, configure to detect error of input data. The control circuit controls the first error detecting circuit to use a first setting to detect the error in a first time period, controls the first error detecting circuit to use a second setting to detect the error in a second time period following the first time period, and controls the first error detecting circuit to generate a first detecting result corresponding to the first setting and the second setting after the detection corresponding to the first setting and the second setting are completed.
