Overview

General logical comparison module

Discussion

This module implements a general purpose logical comparison module that is capable of realizing many different comparison functions. 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 list discusses the various compare operations types,.

compareType = 0, performs logic equal operation.

compareType = 1, performs logic not equal operation.

compareType = 2, performs logic lessthan operation.

compareType = 3, performs logic lessthan equal operation.

compareType = 4, performs logic greaterthan operation.

compareType = 5, performs logic greaterthan equal operation.

Type Definition

typedef struct _ModuleLogicCompare
{
    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
} ModuleLogicCompareClass;

MATLAB Usage

File Name: logic_compare_module.m

 M=logic_compare_module(NAME)
 Creates a general purpose comparison module that implements a number
 of standard logical operations. The module has two input pins, each
 with an arbitrary number of interleaved channels. The module performs
 the comparison on a sample-by-sample basis.  
 
 Arguments:
    NAME - name of the module.
