Opis:
A novel dual mode logic (DML) model has a superior energy-performance compare to CMOS logic. The DML model has unique feature that allows switching between both modes of operation as per the real-time system requirements. The DML functions in two dissimilar modes (static and dynamic) of operation with its specific features, to selectively obtain either low-energy or high-performance. The sub-threshold region DML achieves minimum-energy. However, sub-threshold region consequence in performance is enormous. In this paper, the working of DML model in the moderate inversion region has been explored. The near-threshold region holds much of the energy saving of subthreshold designs, along with improved performance. Furthermore, robustness to supply voltage and sensitivity to the process temperature variations are presented. Monte carol analysis shows that the projected near-threshold region has minimum energy along with the moderate performance.

Opis:
Hierarchical Petri nets beside UML state machine diagrams, sequentional function charts (SFC) and hierarchical concurrent state machines are common solution for specification of logic controllers. These specification formats provide both concurrency and modeling on multi levels of abstraction (hierarchic approach). But only state machine diagrams supports exceptions handling in direct way. Program model presented in form of state machine diagram may be later transformed into a program in the SFC language or transformed in the Petri Net and implemented in the FPGA structure. Similarity between SFC language and Petri Nets give us lot of tools for analysis such control system. Article presents new approach for exceptions handling in hierarchical Petri nets as formal specification for logic controllers. Proposed method of specification can be used independently or as a part of dual specification (correlated state machine diagram and hierarchical configurable Petri Net).

Opis:
In the paper, design flow of the application specific logic controllers with increased safety by means of Petri nets is proposed. The controller architecture is based on duplicated control unit and comparison results from both units. One specification of control algorithm is used by means of Petri net for both units. The hardware duplication is obtained during dual synthesis process. This process uses two different logic synthesis methods to obtain two different hardware configurations for both control units. Additionally, the dual verification is applied to increase reliability of the control algorithm. Such design flow simplifies the process of realization of control systems with increased safety.
