MAC-DO: Charge Based Multi-Bit Analog In-Memory Accelerator Compatible with DRAM Using Output Stationary Mapping

In many applications, a DRAM with a large parallel multiply-accumulate array can maximize the performance of AiM by reducing both the distance and amount of data movement between the processor and the main memory. This paper presents an analog MAC array based AiM architecture called MAC-DO. MAC-DO makes an entire DRAM array participate in MAC calculations simultaneously without idle cells, resulting in higher throughput and energy conservation in comparison to previous in-DRAM accelerators. Without any changes of a DRAM cell and array, MAC-DO is still compatible with new 1T1C DRAM technology. Based on output stationary mapping, a MAC-DO array can speed matrix multiplications based on output stationary mapping, which supports the majority of the calculations done in DNNs. For a MNIST dataset without retraining, an evaluation using transistor-level simulation reveals that a test MAC-DO array of 16 x 16 MAC-DO cells achieves 188. 7 TOPS/W and shows 97. 07% Top-1 accuracy.

A hyper-reduced MAC scheme for the parametric Stokes and Navier-Stokes equations

The classical reduced base method is widely used because of an offline-online deposition and a mathematically precise posterior error estimator that guides a greedy algorithm offline, as well as an offline-based a posterior error estimator that guides a greedy algorithm offline. We present an adaptive enrichment scheme for R2-ROC in this paper, making it suitable for parametric fluid flow conditions. A novel hyper-reduced MAC scheme is now presented and tested on lid-driven cavity and flow through a backward-facing step problem demonstrating its high effectiveness, stability, and accuracy, as a result of its high reliability, stability, and accuracy, which is also shown and demonstrated on top of underlying Marker and Cell scheme.

Effects of MAC Parameters on the Performance of IEEE 802.11 DCF in NS-3

This paper discusses the implementation of the NS-3 script for WLAN that is arranged in accordance with the hierarchical style of TCP/IP's hierarchical structure of the TCP/IP model. To investigate the effects of MAC parameters on performance metrics, we can test all layers by using NS-3 model objects and specify and change the values used by objects. The simulation results show that the RTS/CTS access mechanism outperforms basic access mechanism in an impoverished region, although the MAC parameters have no effect on network performance in a non-saturated state.

Exploration of User Privacy in 802.11 Probe Requests with MAC Address Randomization Using Temporal Pattern Analysis

In this paper, we discuss the evolution of privacy controls in Wi-Fi probe request frames. To get the real ad-dress of the device, we do not want to reverse MAC address randomization, but rather analyze the possibility of further tracking/localization without needing the specific MAC address of the specific users.
