<TR><TD class=Text colspan=3><b>Summary</b><p>The 18X18 multiplier demonstrates
how to generate multipliers of a specific bit width.</p>
<p><b>Description</b></p>
<p>This example shows how you use Impulse C fixed-width data types in
conjunction with C-language features (specifically type casting) to ensure
that the logic generated for your C code is of a specific bit width. Notice
that the fixed-width types co_int18 and co_int36 are used to define the width
of the operands and result, respectively. Notice also that a type cast (in
this case to int64) is used to promote the operands to a larger size prior to
the multiply. The result of this will be a 36-bit multiply, which is highly
efficient for certain FPGA families.</TD></TR>
