Project description: Deep neural networks can be extraordinarily accelerated by using memristive devices as synaptic connections. However, traditionally, the deep neural networks utilize the error backpropagation algorithms, which face some issues when the networks are implemented in hardware based on memristive devices: i) complex peripheral circuits with expensive ADCs and DACs and memory back for intermediate layer states; ii) lack of efficient online training methods. We recently developed an efficient...

Background: Computing-in-memory (CiM) has been a potential solution to break the memory wall and energy wall brought by the conventional computer architecture that separates the computing units and memory units. RRAM-based stateful logic is a kind of CiM that could implement any function in RRAM crossbar array. There are some efficient synthesis and mapping methods for 2D RRAM crossbar array. 3D RRAM crossbar arrays are denser and can support stateful...

The Bitlet model is a new an analytical, parameterized, modeling tool, developed in the ASIC2 lab. The Bitlet model can be used to estimate the performance and the power of a PIM-based system and thereby assess the affinity of workloads for PIM as opposed to traditional computing.In order to make Bitlet more beneficial, it has to be made more accessible to users by equipping it with new features and interactive graphical...

In this project, a thermoelectrical model of the indirectly heated four-terminal PCM RF switch will be developed and verified against experimental data. This model will be useful to accurately predict the behavior of these devices and to simulate large circuits with small computational power.Categories: Analog | ElectroMagnetic/Heat/Mechanical and Device Simulations | Memristors | Memristors | RF

The growing demand to connect the world is pushing wireless systems to be smaller than ever. This is part of the increasing move to a data driven world with billions of connected devices in the era of the Internet of Things (IoT) and space and energy are critical design criteria. Traditionally, miniaturization was possible owing to a focus in a single frequency and a single communication protocol. However, the real...
