The dream to create novel computing hardware that captures aspects of brain computation has occupied the minds of researchers for over 50 y. Driving goals are to carry both the astounding energy efficiency of computations in neural networks of the brain and their learning capability into future generations of electronic hardware. A realization of this dream has now come one step closer, as repo...

Alister Hamilton II Song Han(l) H. Martin Reekie Dept. Electrical Eng. U niv. of Edinburgh We announce new CMOS synapse circuits using only three and four MOSFETsisynapse. Neural states are asynchronous pulse streams, upon which arithmetic is performed directly. Chips implementing over 100 fully programmable synapses are described and projections to networks of hundreds of neurons are made. 1 O...

A mixed analog/digital chip (ANNA) for fast 2-d convolution and matrix-vector multiplication has been developed (peak speed 20,000 MOPS). Two of these chips have been integrated on a 6U VME board, to serve as a high-speed platform for a wide variety of algorithms used in neural-network applications as well as in image analysis. The system has been tested for such tasks as character recognition,...

In this study, changes in some quality parameters of fish chips produced from sand smelt (Atherina boyeri, RISSO 1810) during storage period (at -18  o C for 6 months) were determined.  The difference between the amount of moisture, crude protein, crude fat and crude ash components of raw fish in fish chips was significant (P<0.05). Pre-frying  process resulted in a decrease in all fatty acid c...

a functional treatment for skeletal damages in orthopedic and oral maxillofacial surgeries is required. platelet growth factors such as platelet derived growth factor (pdgf), bone morphogenic factor (bmp), transferring growth factor-β (tgf-β) and insulin-like growth factor-1 (igf-1) proceed wound healing and bone regeneration. in the present study we focused on the effect of platelet rich plasm...

......Welcome to the March/April issue of IEEE Micro, which is devoted to a set of articles summarizing some of the best presentations at the latest Hot Chips symposium. The Hot Chips special issue has been a tradition for several decades now and is an excellent opportunity to report on some of the cuttingedge microprocessor designs and projects in industry, research labs, and academia. Hot Chi...

pepino (solanum muricatum), a new vegetable crops, is from solanaceae family and cultivated as annual crops. in order to investigate the effects of mulch on weed dry weight in pepino and soil humidity and temperature, an experiment was conducted based on randomized completely design with three replication at the ferdowsi university of mashhad green house, during 2009. treatments included rice s...

The address-event representation (AER) is an asynchronous point-to-point communications protocol for silicon neural systems. This paper describes an extension of the AER protocol that allows multiple AER senders to share a common bus. A fully-functional silicon implementation of the extended protocol is described, as well as a functional board-level system of several of these chips sharing a co...

A Gaussian/square function computation circuit suitable for analog neural networks is proposed. It can realize Gaussian and square functions when operating in weak and strong inversion region, respectively. It is shown that the center, width, and peak amplitude of the dc transfer curve can be controlled separably. Measurement results on 3m CMOS fabricated chips confirm theoretical and simulatio...

The AI chips increasingly focus on implementing neural computing at low power and cost. intelligent sensing, automation, edge applications have been the market drivers for chips. Increasingly, generalisation, performance, robustness, scalability of chip solutions are compared with human-like intelligence abilities. Such a requirement to transit from application-specific general must consider se...
