In this paper, we propose a novel architecture for a reconfigurable networks on chip (NoC)-based platform called OperaNP. In this platform, intellectual property (IP) cores can be embedded on an array of programmable logic blocks while the data routing is done using another array of configurable routers. A programmable switch fabric is designed to connect(More)
This paper presents a new technique for studying backoff strategies in wireless access control protocols. The technique is applied to develop discrete-time Markov chain models for three wireless MAC protocols: pure ALOHA, slotted ALOHA and CSMA/CA. Network throughput is investigated for the protocols. It was found that optimum performance of the MAC(More)
We propose a novel, low-area, high-speed architecture for the basic operations over GF(2<sup>m</sup>). The proposed architecture is a processor array based, which utilizes the most significant bit multiplication algorithm and polynomial basis. A design space exploration to optimize the area and speed of the proposed architecture was done. We use the(More)
