Placement of functional units on an FPGA fabric is a challenging problem for runtime reconfigurable computing systems. We introduce the concept of physical contexts to greatly reduce the complexity of the placement and routing problems. We have implemented static and dynamic linear placement methods for expression trees placed in physical contexts. Our placement algorithms are implemented in th...

This study designed a multi-functional reconfigurable transmitarray with switchable polarization and beam steering capabilities using only PIN diode having ON/OFF switching ability. The simulation confirmed that the proposed architecture is capable of 2D scanning up to ±45° for elevation azimuth while maintaining or converting linear when operating within X-band. performance was verified throug...

Self-reconfigurable robots are an instance of complex systems that can autonomously rearrange their modules. Recently, there has been a great interest in using these robots in different domains such as reconnaissance, rescue missions, and space applications for their versatility, fault tolerance, low cost of reproducibility, and efficiency in rough terrains. Because of their distributed nature,...

Performance requirements for on-board processing of satellite instrument data are steadily increasing. This demonstrator shows how today’s SoCs for satellite payload processing can be extended with high-speed interfaces and computing power utilizing commercial dynamically reconfigurable FPGAs. Reconfigurable hardware further allows for changing or adapting payload processing during the flight m...

Reconfigurability is a recent research topic. It enables terminals and network elements to dynamically change their functional behaviour in order to optimize jointly performance and computational requirements. It is a multidimensional concept and its algorithmic and hardware expressions generate confusion in definition. In this paper, we try to clarify these confusing terms by defining reconfig...

To respond quickly to the rapidly changing manufacturing environment, it is imperative for the system to have such capabilities as flexibility, adaptability, and reusability. The fractal manufacturing system (FrMS) is a new manufacturing paradigm designed to meet these requirements. Through its dynamic restructuring process (DRP), the FrMS is able to reorganize the system’s configuration by its...

Modern embedded systems have an emerging demand on high performance and low power circuits. Traditionally special functional units for each application are developed separately. These are plugged to a general purpose processors to extend its instruction set making it an application specific instruction set processor. As this strategy reaches its boundaries in area and complexity reconfigurable ...

There is a clear turning point in the development history of reconfigurable architectures. Larger execution units (EU) used to be adopted in special domain applications to improve the cost performance of programmable architectures. However, after the granularity of EUs came up to the level of arithmetic logic unit (ALU) and multiplication accumulation unit (MAC), the trend almost stopped. At pr...

ÐSeveral new number representations based on a Residue Number System are presented which use the smallest prime numbers as moduli and are suited for parallel computations on a reconfigurable mesh architecture. The bit model of linear reconfigurable mesh with exclusive write and unit-time delay for broadcasting on a subbus is assumed. It is shown how to convert in O…1† time any integer, ranging ...

In this study, a radiation pattern reconfigurable microstrip antenna is designed and fabricated. The antenna’s radiation pattern is directed in 9 different angles by employing a radiating patch and embedding complementary split ring resonators (CSRR) on the ground plane. The radiating patch is of circular shape, while for CSRR elements both circular and rectangular shapes are investigated. The ...
