We consider a model of reconfigurable robot, introduced and prototyped by the robotics community. The robot consists of independently manipulable unit-square atoms that can extend/contract arms on each side and attach/detach from neighbors. The optimal worst-case number of sequential moves required to transform one connected configuration to another was shown to be Θ(n) at ISAAC 2007. However, ...

The ability of a compiler to exploit loop-level parallelism in a reconfigurable array is significantly affected by the amount of flexibility in the interconnect architecture. A less flexible interconnect will make it more difficult for the compiler to find efficient loop-level pipelined schedules, leading to reduced instruction throughput, and larger configuration bit storage area. In this pape...

Application-specific optical processors have been considered disruptive technologies for modern computing that can fundamentally accelerate the development of artificial intelligence (AI) by offering substantially improved performance. Recent advancements in neural network architectures information processing applied to perform various machine learning tasks. However, existing limited complexit...

Wearable computers are embedded into the mobile environment of the human body. A design challenge for wearable systems is to combine the high performance required for tasks such as video decoding with low energy consumption required to maximize battery runtimes and the flexibility demanded by the dynamics of the environment and the applications. In this paper, we demonstrate that reconfigurable...

This paper introduces a new datapath architecture for reconfigurable processors. The proposed datapath is based on Network-on-Chip approach and facilitates tight coupling of all functional units. Reconfigurable functional elements can be dynamically allocated for application specific optimizations, enabling polymorphic computing. Using a modified network simulator, performance of several NoC to...

Reconfigurable computing devices have achieved substantial performance improvements over conventional processors on some computational kernels. These benefits derive from hardware customization which avoids the mismatch between the basic requirements of the algorithms and the architectures of the processors. A reconfigurable fabric alone is not sufficient for general-purpose computing since it ...

We introduce algorithms for optimizing a single-input single-output reconfigurable intelligent surface (RIS) assisted system. The RIS is modeled by using an electromagnetic-compliant framework based on mutual impedances and its reconfigurability realized through tunable lumped impedances. In the absence of coupling among scattering elements RIS, we derive closed-form expression optimal impedanc...

In this paper we design a new reconfigurable controller for active fault-tolerant control systems with direct applicability to aircraft’s flight control. The reconfigurable controller is based on a new algorithm for the calculation of the controller gain matrix without using information from a full-order or reduced order observer. The main advantages of the reconfigurable controller, when no fa...

Sensor technology continues to improve at the price of increased data rates, which require being processed. In the space domain, the available bandwidth for effectively transferring the data to the base station is limited, such that there is a need for a high-performance data processing unit on board of the spacecraft. This work targets the development of a scalable high-performance payload dat...
