Overview

Compares the value at the input pin against a stored value

Discussion

This module implements a general purpose logical compare module against stored integer value that is capable of realizing many different logic operations. The behavior of the logic compare is controlled by the compareType parameter. compareType is an integer in the range from 0 to 5 inclusive. The following listdiscusses the various compare oprations types and which variables are active in each case. compareType = 0, performs logic equal operation.

compareType = 1, performs logic not equal operation.

compareType = 2, performs logic less than operation.

compareType = 3, performs logic less than equal operation.

compareType = 4, performs logic greater than operation.

compareType = 5, performs logic greater than equal operation.

For example, when compareType == 2, the output pin equals the Boolean value (input < constValue)

Type Definition

typedef struct _ModuleLogicCompareConstInt32
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    INT32 compareType;                            // Selects the type of comparison that is implemented by the module: Equal=0 NotEqual=1 lessThan=2 LessOrEqual=3 greaterThan=4 GreaterOrEqual=5
    INT32 constValue;                             // Selects value against to compare against. In linear integer units.
} ModuleLogicCompareConstInt32Class;
