Abstract

Zgłoszenie dotyczy arbitra (ARB) metastabilnościowego generatora losowego i sposobów regulacji pracą arbitra, zbudowanego z dwóch przerzutników (P1, P2) komplementarnie podłączonych do jego wejść (i1-A, i2-A), oraz elementów logicznych (AND, NOT, XNOR) dołączonych do wyjść przerzutników (Q1, Q2) i zamieniających pierwszeństwo na logiczne wartości oraz wykrywających wewnętrzny błąd arbitrażu. Wskutek błędu odcinane jest wyjście arbitra (o-A) przez bufor trójstanowy (B), a błędy arbitrażu zapisywane są w rejestrze przesuwnym. Pracą przerzutników steruje układ kompensacji i regulacji (UKR), który dzięki specjalnej budowie przerzutników pozwala na: regulację szybkości jednego przerzutnika względem drugiego, regulację pracy między stopniem master i slave w każdym przerzutniku, równoważenie pracy każdego stopnia każdego przerzutnika, wzorcowanie arbitra, kompensację w trakcie pracy, czy regulację pobieranej mocy. Dzięki wynalazkowi możliwa jest kompensacja rozrzutów technologicznych, zmiana położenia i rozmiaru okna metastabilności, regulacja wpływu szumu fazowego, redukcja czasu regeneracji, kompensacja wpływu starzenia się i pracy mechanicznej czy oddziaływania czynników środowiskowych.This application concerns an arbitrator (ARB) for a metastability random generator and methods for regulating the operation of an arbitrator. The arbiter consists of two flip-flops (P1, P2) complementarily connected to its inputs (i1-A, i2-A), and logical elements (AND, NOT, XNOR) connected to the flip-flop outputs (Q1, Q2), converting priority to logical values and detecting an internal arbitration error. As a result of an error, the arbiter output (o-A) is cut off by a three-state buffer (B), and arbitration errors are stored in a shift register. The operation of the flip-flops is controlled by a compensation and regulation circuit (UKR), which, thanks to its special design, allows for: speed regulation of one flip-flop relative to the other, regulation of the master and slave stages in each flip-flop, balancing the operation of each stage of each flip-flop, calibration of the arbiter, compensation during operation, and power consumption regulation. Thanks to the invention, it is possible to compensate for technological dispersion, change the position and size of the metastability window, regulate the influence of phase noise, reduce the regeneration time, compensate for the influence of aging and mechanical work, or the impact of environmental factors.
