Three generations of Alpha microprocessors have been designed using a proven custom design methodology. The performance of these microprocessors was optimized by focusing on high-frequency design. The Alpha instruction set architecture facilitates high clock speed, and the chip organization for each generation was carefully chosen to meet critical paths. Digital has developed six generations of...

In Australia, as electricity prices have increased, driven mainly by increases in peak demand, electricity use has decreased every year since 2008/09. The factors most responsible for these decreases include increased electricity costs, energy efficiency, solar water heaters and photovoltaics. Further increases in electricity prices and uptake of these technologies could result in further reduc...

R ecent surveys in the U.S., Britain, Australia, and other OECD nations continue to report unacceptably high ,levels of adult illiteracy (Australian Bureau of Statistics, 1997a, 1997b). In the present context of unprecedented growth in symbolic sophistication associated with the current technological revolution (Castells 1996, 1997), claims of widespread adult illiteracy in "advanced" societies...

T he Next Generation Science Standards (NGSS), due to be released this spring, represents a revolutionary step toward establishing modern, national K–12 science education standards. Based on the recommendations of the National Research Council’s A Framework for K–12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (NRC 2012), these performance expectations present a progressi...

This paper introduces a novel technique for synthesis of speed-independent circuits from their Signal Transition Graph specifications. The new method uses partial order in the form of the STG-unfolding segment to derive the logic implementation using approximation techniques. It is based on a new notion of slice, which localises the behaviour of a particular signal instance in a structural frag...

For synthesising efficient asynchronous circuits from STGs one has to deal with the state space explosion problem. For this purpose STG decomposition was introduced by Chu and improved by Vogler and Wollowski. Here, we present the tool DesiJ which is the implementation of STG decomposition and proposed by Vogler and several other optimisations.

Digital Equipment's Paris Research Laboratory started to investigate the use of FPGA-based re-conngurable hardware accelerators in 1988. We call them PAMs for Programmable Active Memories. Over the past six years, we have designed and implemented four generations of PAM hardware and four generations of PAM programming environments. Several dozen people, ranging from inexperienced students to se...

A farmed population of rainbow trout under selection for over six generations from the Norwegian Salmon Breeding Company, Ltd. was investigated for levels of inbreeding and occurrence of inbreeding depression for body weight. The average percent inbreeding levels and percent of individuals with inbreeding greater than zero (in parenthesis) were 2.9 (59.3), 2.8 (49.8), 8.5 (87.1), 8.0 (82.8) and...
