1.5. Data Compression Comparison

Standard compression results in a 30-45% decrease in .rbf size. Use of the enhanced data compression algorithm results in 55-75% decrease in .rbf size. The algorithm increases the compression at the expense of additional core area required to implement the compression algorithm.

The following figure shows the compression ratio comparison across PR designs with varying degrees of Logic Element (LE):
