Protocol Transducer Synthesis using Divide and Conquer Approach
2007 Asia and South Pacific Design Automation Conference, 2007Co-Authors: Shota Watanabe, Kenshu Seto, Yuji Ishikawa, Satoshi Komatsu, Masahiro FujitaAbstract:One of the efficient design methodologies for large scale system on a chip (SoC) is IP-based design. In this methodology, a system is considered as a set of components and interconnects among them. The designers try to reuse existing IPs as much as possible. Communications among components have to be conducted using a common protocol, however, IPs available today use various communication protocols. Thus the protocol conversion is one of the most important topics in IP-based design (Gajski et al., 2000). In this paper, we propose a method for automatic protocol transducer synthesis which is applicable to complex protocols. The main idea of our proposed method is division of the exploration space into smaller ones for avoiding explosion of the exploration space, namely with a divide and Conquer Approach. We demonstrate our method by synthesizing transducers which translate between the real and complicated protocols with advanced features such as non-blocking transactions and out-of-order transactions.

Joint Tx/Rx Energy-Efficient Scheduling in Multi-Radio Wireless Networks: A Divide-and-Conquer Approach
IEEE Transactions on Wireless Communications, 2016Co-Authors: Meixia Tao, Wen ChenAbstract:Most of the existing works on energy-efficient wireless communications only consider the transmitter (Tx) or the receiver (Rx) side power consumption, but not both. Moreover, the circuit power consumption is often assumed to be constant regardless of the transmission rate or the bandwidth. In this paper, we investigate the system-level energy-efficient transmission in multi-radio access networks by considering joint Tx and Rx power consumption and adopting link-dependent dynamic circuit power model. A combinatorial-type optimization problem for user scheduling, radio-link activation, and power control is formulated with the objective of maximizing joint Tx and Rx energy efficiency (EE). We tackle this problem using a divide-and-Conquer Approach. Specifically, the concepts of link EE and user EE are first introduced, which have structures similar to the system EE. Then, we explore their hierarchical relationships and propose an optimal algorithm whose complexity is linear in the product of the total number of users and radio links. Furthermore, we investigate the EE maximization problem with minimum user data rate constraints. The divide-and-Conquer Approach is also applied to find a sub-optimal but efficient solution. Finally, comprehensive numerical results are provided to validate the theoretical findings and demonstrate the effectiveness of the proposed algorithms.

joint tx rx energy efficient scheduling in multi radio networks a divide and Conquer Approach
International Conference on Communications, 2015Co-Authors: Meixia Tao, Wen ChenAbstract:Most of the existing works on energy-efficient wireless communication systems only consider the transmitter (Tx) or the receiver (Rx) side power consumption but not both. Moreover, they often assume the static circuit power consumption. To be more practical, this paper considers the joint Tx and Rx power consumption in multiple-access radio networks, where the power model takes both the transmission power and the dynamic circuit power into account. We formulate the joint Tx and Rx energy efficiency (EE) maximization problem which is a combinatorial-type one due to the indicator function for scheduling users and activating radio links. The link EE and the user EE are then introduced which have the similar structure as the system EE. Their hierarchical relationships are exploited to tackle the problem using a divide-and-Conquer Approach, which is only of linear complexity. We further reveal that the static receiving power plays a critical role in the user scheduling. Finally, comprehensive numerical results are provided to validate our theoretical findings and demonstrate the effectiveness of the proposed algorithm for improving the system EE.
