Q & A
What is the main topic of Orange Banerjee's seminar presentation?
-The main topic of Orange Banerjee's seminar presentation is neuromorphic computing.
Which university is Orange Banerjee pursuing his V-Tech in CSE from?
-Orange Banerjee is pursuing his V-Tech in CSE from Bennett University.
What is the von Neumann architecture and why is it significant in the context of neuromorphic computing?
-The von Neumann architecture is a computer architecture where the CPU and memory are separate, which leads to a bottleneck in data transfer. It's significant in neuromorphic computing because it contrasts with the human brain's architecture, which is more efficient and does not have such a bottleneck.
Who invented neuromorphic computing and what is its main principle?
-Neuromorphic computing was invented by Carver Mead in the 1980s. Its main principle is to create integrated circuits that replicate or mimic the neurobiological architecture present in the human nervous system.
What is Moore's Law and how does it relate to neuromorphic computing?
-Moore's Law states that the number of transistors on a microchip doubles every two years, and the cost of computers is halved. It relates to neuromorphic computing as it highlights the exponential growth of technology, which is challenged by the energy inefficiency of traditional architectures, making the energy-efficient neuromorphic systems more appealing.
Why is there a need for neuromorphic systems according to the presentation?
-There is a need for neuromorphic systems because traditional von Neumann architecture is energy-hungry and faces limitations in processing power and efficiency, especially when compared to the human brain's capabilities.
What is a memristor and how does it relate to neuromorphic computing?
-A memristor is an electrical device that remembers the amount of current or voltage that has passed through it. It is crucial in neuromorphic computing because it can mimic the synaptic behavior found in the human brain, allowing for the creation of artificial synapses.
What is the potential impact of neuromorphic computing on space operations?
-Neuromorphic computing can make space missions more efficient by reducing the need for ground mission teams, as it allows space vehicles to adapt and learn according to their environment, thus requiring less power and processing capabilities.
What are some of the challenges faced in developing neuromorphic systems?
-Challenges in developing neuromorphic systems include designing and analyzing the structure, creating new programming languages, and developing new generations of memory storage and sensor technologies.
What are the two neuromorphic systems mentioned in the presentation, and what are their key differences?
-The two neuromorphic systems mentioned are the Neural Grid and IBM's TrueNorth. The Neural Grid uses sub-threshold analog logic and is smaller in scale, while TrueNorth is larger, more efficient, and uses digital memristor devices instead of traditional VLSI systems.
How does the efficiency of the human brain compare to modern supercomputers in terms of processing power?
-The human brain is significantly more efficient than modern supercomputers. It can process around 10^18 floating points per second on just 20 watts of power, making it five times faster than the world's largest supercomputer, which is IBM's Summit.
