For most multi-modal stream processing tasks Dynamic Reconfigurable Systems-on-Chip (SoC) have demonstrated high efficiency in cost and power. These systems utilize partial reconfiguration for dynamic adaptation to changes in the workload or in environment. Mostly, reconfiguration mechanisms are based on central resource management sub-systems deployed in a(More)
The conception of Network-on-Chip (NoC) presents system designers with a new approach to the design of on-chip interconnection structures. However, such networks present designers with a large array of design parameters and decisions, many of which are critical to the efficient operation of NoC systems. To aid the design process of complex systems-on-chip,(More)
Field-Programmable Gate Arrays (FPGAs) are rapidly gaining popularity as implementation platforms for complex space-borne computing systems. However, such systems are exposed to cosmic radiation with levels orders of magnitude higher than terrestrial levels which can cause transient and even permanent hardware faults in on-board computing platforms. Because(More)
This paper presents a new approach to meeting communication requirements of on-chip network systems. The method is based on the transaction-oriented protocol employed by on-chip components, and the fact that latency becomes the performance-impacting factor instead of bandwidth. A network-on-chip topology generation and analysis tool is presented which has(More)
The concept of hardware resource virtualization which was initiated in virtual memory organization has recentlyexpanded towards virtualization of computing resources inpartially reconfigurable FPGAs. However, this kind of resource virtualization requires mechanisms for flexible allocation/relocation of components associated with data execution processes.(More)
Dynamic Partially Reconfigurable Computing(DPRC) systems have received significant attention in recent years as a potential alternative to traditional computing system designs; such systems implement much of their functionality in the form of virtual components, represented by configuration bit-streams. However, for such systems to be adopted as viable(More)
