Athena Signal Array Processors (ASAP) are the foundation of Athena signal Processing technology. By harnessing the power of the Residue Number System (RNS), Athena created a fundamentally new way of implementing high-speed arithmetic in silicon. Athena signal processing technology is largely based on the advances developed under the ASAP development program, and this technology has directly resulted in state of the art advances in high-precision applications. Athena Public Key technology relies directly upon the ASAP technology to achieve up to 100x the performance density, or performance per unit area, of any other PK product on the market.
