Abstract
A computer-based system and method for efficiently identifying inverted bits in an address, utilizing a single technique to rearrange any size table, generating new index bit sequences based upon inverted index bits without utilizing a significant amount of memory resources, and rearranging table entries only once. The present invention utilizes a mask that defines the address bits that are inverted for a new table. The present invention then rearranges the table entries in the old table to form a new table. Once generated the new table can be used in place of the old table thereby requiring no more memory than the old table. Accordingly, the present invention provides a system and method for identifying the index bits to be inverted after the lookup table and computer program have been generated while utilizing significantly less memory than conventional systems and methods.
