Requirement-based design methods for adaptive communications links

High-speed communications link cores must consume low-power, feature, low bit-error-rates (BER), and address many applications. We pFsent a methodology to design adaptive link architectures, whereby the link´s intemal logic complexity, frequency, and supply are simultaneously adapted to application requirements. The requirement space is mapped to the design space using requirements measurement circuits and configurable logic blocks. CMOS results indicatk that power savings of 60% versus the worst case arc Dossible. while the area overhead is keot under 5%.
