The proposal by Hubbard et al. (1) that "Very High Alumina basalt" ("VHA basalt") may represent an important primary lunar magma type neglects consideration of certain well-characterized high-magnesium highland rocks, among them spinel troctolite from Luna 20 (2) and Apollo 16 samples (3) and dunite from Apollo 17 samples (4), and the possibility that "VHA basalt" may in fact have originated by...

Fault-tolerance increases hardware reliability of a VLSI design but it also has the disadvantage of increasing chip area. This area overhead can however be minimized by consideration of fault-tolerance during the high-level synthesis stage of design. We introduce an intertwined scheduling and binding algorithm for self-recovering fault-tolerant designs. Two copies in a self-recovering design ha...

In deep submicron era, wire delay is no longer negligible and is becoming a dominant factor of the system performance. To cope with the increasing wire delay, several state-of-the-art architectural synthesis flows have been proposed for the distributed register architectures by enabling on-chip multicycle communication. In this article, we present a new performance-driven criticality-aware synt...

Characteristics of the data being processed can be used to reduce the power consumption in the data path of a VLSI circuit by exploiting their relationship with transition activity during highlevel synthesis. Important relationships between fixed-point, two’s complement data characteristics and 0→1 transition activity in static CMOS circuits are presented in this paper. Models for computing tra...

Abstract: macros that can be embedded into synchronous circuitry was This paper presents a Scan path design to ease the controllability presented in [89LeenS]. To test the asynchronous modules a and observability of Self-timed logic. The Scan path registers synchronous scan test is presented there. In contradiction, the operate in asynchronous mode during operation and test. asynchronous machin...
