Visual Sensor Networks (VSNs) are networks which generate two dimensional data. The major difference between VSN and ordinary sensor network is the large amount of data. In VSN, a large number of camera nodes form a distributed system which can be deployed in many potential applications. In this paper we present a model of the physical parameters of a(More)
Access to the published version may require subscription. A visual sensor network (VSN) is a distributed system of a large number of camera nodes and has useful applications in many areas. The primary difference between a VSN and an ordinary scalar sensor network is the nature and volume of the information. In contrast to scalar sensor networks, a VSN(More)
We have separated the information required for HW/SW interface synthesis into three parts, the protocol specification, the operating system related information, and the processor related information. From these inputs a synthesis tool generates (a) device driver functions or (b) a combination of device driver functions and a DMA controller, depending on a(More)
In this paper we have explored different possibilities for partitioning the tasks between hardware, software and locality for the implementation of the vision sensor node, used in wireless vision sensor network. Wireless vision sensor network is an emerging field which combines image sensor, on board computation and communication links. Compared to the(More)
ProGram, a grammar based communication protocol description language, is used for architectural independent modelling of device drivers and bus interfaces for mixed hardwarehoftware systems. The specijication of the protocol is separated from the description of processor bus interfaces and operating system device driver interfaces, which ensures a high(More)
We present a method for generation of the software part of a HW/SW interface (i.e. the device drivers), which separates the behaviour of the interface from the architecture dependent parts. We do this by modelling the behaviour in ProGram (a grammar based protocol specification language) and capture the processor and OS kernel parts in separate libraries.(More)
We present an architecture for rapid prototyping of selected control-dominated HW parts resulting from HW/SW cosynthesis. Our codesign toolkit AKKA[1], which targets to design of control intensive systems, consists of design space exploration, estimation, partitioning, cosimulation and verification subtools in common environment. For fast prototyping of HW(More)
