Position Paper:Defending Direct Memory Access with CHERI Capabilities [PDF]

Hardware and Architectural Support for Security and Privacy, 2020
We propose new solutions that can efficiently address the problem of malicious memory access from pluggable computer peripherals and microcontrollers embedded within a system-on-chip. This problem represents a serious emerging threat to total-system computer security.

Design and Implementation of a Direct Memory Access Controller for Embedded Applications

International Journal of Technology, 2019
In this paper, we propose a design and implementation of a Direct Memory Access Controller (DMAC) as a part of an SoC. The main purpose of the DMAC design is to integrate it into a System on a Chip (SoC) for the exchange of a large volume of data ...

Hardware Based Security Enhanced Direct Memory Access [PDF]

Communications and Multimedia Security, 2013
This paper presents an approach to prevent memory attacks enabled by DMA. DMA is a technique that is frequently used to release processors from simple memory transfers. DMA transfers are usually performed during idle times of the bus. A disadvantage of DMA transfers is that they are primarily unsupervised by anti malware agents. After the completion of

A High-Speed Dynamic Partial Reconfiguration Controller Using Direct Memory Access Through a Multiport Memory Controller and Overclocking with Active Feedback

International Journal of Reconfigurable Computing, 2011
Dynamically reconfigurable computing platforms provide promising methods for dynamic management of hardware resources, power, and performance. Yet, progress in dynamically reconfigurable computing is fundamentally limited by the reconfiguration time ...

Memory Management Support for Multi-Programmed Remote Direct Memory Access (RDMA) Systems [PDF]

2005 IEEE International Conference on Cluster Computing, 2005
Current operating systems offer basic support for network interface controllers (NICs) supporting remote direct memory access (RDMA). Such support typically consists of a device driver responsible for configuring communication channels between the device and user-level processes but not involved in data transfer.

CNN-DMA: A Predictable and Scalable Direct Memory Access Engine for Convolutional Neural Network with Sliding-window Filtering

ACM Great Lakes Symposium on VLSI, 2021
Memory bandwidth utilization has become the key performance bottleneck for state-of-the-art variants of neural network kernels. Current structures such as depth-wise, point-wise and atrous convolutions have already introduced diverse and discontinuous ...
