Reducing the Memory Footprint of Your Powertrain System

Using a Powertrain system example, this video demonstrates the lookup table optimization capability that enables you to compress the lookup tables in your design to reduce the RAM memory usage. You can approximate a function or an existing block with an optimal lookup table.

Designing an optimal lookup table involves various choices: fixed-point or floating-point data, size of the table, evenly spaced data or uneven spacing, and other algorithm settings such as the interpolation method. All these decisions are automated using the lookup table optimizer.

We explore the tradeoff between system behavior and efficient design as measured by the amount of memory reduced.
