Programmable impulse neural circuits

A description is given of CMOS electronic circuits which emulate natural neurons at a more detailed level than that typically used by artificial neural network models. A pulse-firing circuit which realizes general short-term neuron dynamics is discussed. Both fixed and programmable synapse circuits for realizing long-term dynamics are also described. Together, these establish the basic structures required for the implementation of programmable impulse neural networks.

The Impact of Providing Unlimited Access to Programmable Boards in Digital Design Education

This paper presents the benefits and costs of providing students with unlimited access to programmable boards in digital design education, allowing hands-on experiences outside traditional laboratory settings. Studies were conducted at three universities in two different countries-Rose Hulman Institute of Technology, Terre Haute, IN; Washington State University, Pullman; and Technical University of Cluj-Napoca, Romania-to measure the effect on student learning and student performance of students having their own programmable hardware systems and unrestricted access to the most commonly used design tools. The results of the studies, supported by assessment data from various sources, suggest that the overall learning process is improved, and students gain a better knowledge of modern technologies and design methods if they are given full time access to programmable logic boards.

Improving students' hardware and software skills by providing unrestricted access to state of the art design tools and hardware systems

The technology and CAD tools employed by industry to design digital hardware evolve quickly and continuously. Well prepared engineers, who are able to produce actual designs and adapt themselves to the global world, are in demand. Educational programs must keep pace with technologies in common use in order to produce graduates who are competitive in the marketplace. Studies conducted at two different universities, Rose Hulman Institute of Technology and Washington State University measure changes in student performance when all students have unlimited access to state of the art design tools and hardware systems. Data are collected from surveys, exams, and course assignments. Quantitative data are analyzed by comparison to historical data gathered from student groups that did not have unlimited access to hardware systems, and qualitative data are used to determine the subjective quality of each students experience. Outcomes include: assessing whether the overall learning process is improved; whether students have a better knowledge of modern technologies and design methods; whether their comprehension of founding concepts has improved or faltered.

An impulse realization of short-term-memory dynamics

Impulse neural networks use pulse sequences to communicate instantaneous neuron activation levels. CMOS electronic circuits which emulate chemical and voltage-gated membrane channels and communicate in a fashion similar to that of natural neurons are described. These circuits require less area and dissipate less power than the operational amplifier realizations previously used for continuous-time neural network implementation. An impulse network which realizes general short-term memory dynamics is discussed.<<ETX>>
