Logic Binary Op Combination

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.

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.
