Overview
Table lookup where the input serves as an index into a lookup table
Discussion
Performs table lookup where the input pin is treated as an integer index. The length of the lookup table L is specified at instantiation time. The data on the input pin is clipped to the range [0 L-1] and then used as an index into the lookup table. The lookup table contains floating-point values and these are output.
When bypassed the module is still active and continues to perform the look up function.
