Flying-Adder on-chip frequency synthesis architecture

The construction of on-chip clock circuitry has great impact on both system performance and chip implementation cost. Among the many aspects of the clock circuitry, the most important one is its capability of producing frequencies. Flying-adder frequency synthesis architecture, one of the latest developments in clock generation circuitry, is such a circuit-level enabler which can help circuit designers and system engineers to create better-performance and/or lower-cost systems. With this technique, many system and software level issues can be investigated from new directions. Compared to the conventional techniques, this method is capable of generating much more frequencies. Furthermore, it provides great controllability to software so that software programmers have the flexibility of creating novel approaches to differentiate their products from the competitorspsila. In this tutorial, the flying-adder architecture will be first introduced. Then, several real systems are used to demonstrate the power of this new frequency synthesis technique.
