Asynchronous circuits have many advantages vs synchronous design styles like high performance and lower power consumption; however, there is a drawback of big overhead in handshake circuitry of these circuits. In this paper, we have reduced the amount of these extra circuits by take advantage of some compiler techniques. The compiler methods can be used innovatively to improve the synthesis results...
Network-on-chip (NoC) is a precious approach to handle huge number of transistors by virtue of technology scaling to lower than 50 nm. Virtual channels have been introduced in order to improve the performance according to a timing multiplexing concept in each physical channel. The incremental effect of virtual channels on power consumption has been shown in literatures. The issue of power saving has...
Traffic models exert different message flows in a network and have a considerable effect on power consumption through different applications. So a good power analysis should consider traffic models. In this paper we present power and throughput models in terms of traffic rate parameters for the most popular traffic models, i e. Uniform, local, HotSpot and First Matrix Transpose (FMT) as a permutational...
Asynchronous microprocessors are more flexible to adapt to physical parameters, and have lower power consumption than synchronous microprocessors. In this paper we will introduce the design of an asynchronous microprocessor (V8-uRISC) and explore its design process compared to synchronous design. The processor is synthesized by Persia, an automatic tool for synthesizing asynchronous circuits. We have...
Technology scaling increases clock rates and die sizes; therefore, power dissipation is predicted to soon become the key limiting factor on the performance of single-chip designs. NoC as an efficient and scalable on-chip communication architecture for SoC architectures, enables integration of a large number of computational and storage blocks on a single chip. Since different applications impose different...
