Overview

Performs logical operations on binary signals

Discussion

This module can compute multiple binary operations sequentially and write the result in a defined output channel. The output is then a channel integer signal that is formed as the binary operation applied over defined input and output channels.

For example: Out[0] = ( ( ( In[1]&In[3] ) | In[0] ) & In[2] ). The array variable .binaryOpConfig determines the type of binary operation. Possible values are: 0 = AND, 1 = OR, 2 = XOR, 3 = NAND, 4 = NOR, 5 = XNOR. The binary operation is applied on a bit-by-bit basis to the 32-bit signals. 6 = CONST copies the value from the input to the output. Column 1 contains the input channel index (zero-based). Column 2 contains the output channel index (zero-based). Column 3 specifies which binary operation should be performed

This module supports only control data of block size = 1.

    INT32 numOut;                                 // Number of output channels
    INT32 numOps;                                 // Number of binary operations to be computed
    INT32 defaultOut;                             // Defines the default output value for unsused channels
    INT32* binaryOpConfig;                        // Column 1: Input channel index, Column 2: Output channel index, Column 3: AND=0, OR=1, XOR=2, NAND=3, NOR=4, XNOR=5, CONST=6. Selects the type of binary operations that is performed.

MATLAB Usage

File Name: logic_binary_op_combination_module.m

 Creates a module that performs Boolean binary operations (AND, OR, XOR)
 on one or more integer values.
 The module performs the operation on a block-by-block basis. The third 
 argument specifies how many operations are performed.
 The module has one input pin with an arbitrary number of interleaved 
 channels and one output pin with a user defined number of channels.
 Arguments:
    NAME - name of the module.
    NUMOUT - number of output channels. By default 5.
    NUMOPS - number of operations to compute. By default 5.
