LogicCompareConstFract32

Overview

Compares fract32 values against a constant parameter value

Discussion

This module implements a general purpose logical compare module that is capable of realizing many different logic operations. The behavior of the logic compare is controlled by the compareType parameter. filterType is an integer in the range from 0 to 5 inclusive. The following list discusses 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 lessthan operation.

compareType = 3, performs logic lessthan equal operation.

compareType = 4, performs logic greaterthan operation.

compareType = 5, performs logic greaterthan equal operation.

Type Definition

CODE

    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    INT32 compareType;                            // Selects the type of compare that is implemented by the module: Equal=0 NotEqual=1 lessThan=2 LessOrEqual=3 greaterThan=4 GreaterOrEqual=5
    fract32 const_value;                          // Selects value against to perform compare operations

CODE

 M=logic_compare_const_fract32_module(NAME)
 Creates a general purpose compare module that implements a number
 of standard logical operations.  The module operates on multiple interleaved
 channels, with all channels being processed. 
 Arguments:
    NAME - name of the module.
 The module has the following variables that control the design:
   compareType - integer specifying the type of the design (details below).
 The argument compareType determines what design routine is run, and not
 all input arguments are used in all cases:
   0 = performs logical  equal operation
   1 = performs logical  not equal operation
   2 = performs logical  less than operation
   3 = performs logical  less than equal operation
   4 = performs logical  greater operation
   5 = performs logical  greater than equal operation
