Remotely reconfigurable hardware–software platform with web service interface for automated video surveillance

Rapid Embedded Systems Prototyping - an effective approach to embedded systems development

“…The reconfiguration allows developers and maintenance staff not only to remotely update firmware, but also to change the functionality of the system [4]. For example the FPGAaccelerated smart camera described in [5] is able to run multiple configurations which can be substituted depending on a higher level adaptation policy. Enhancing an FPGA-based device with the remote reconfiguration feature costs design issues due to losing the programmable logic functionality during the reconfiguration process [6].…”

“…Bootloader is not required during initial development, and can be added at later development stages. Remote FPGA reconfiguration, programmable logic partial reconfiguration with traditional design flow approach [5], [6], [7], [8] Complex design which includes a reconfiguration subsystem and more elaborate design flow when considering partial reconfiguration.…”

Reconfigurable FPGA-based embedded Web services as distributed computational nodes

“…During the course of our research we developed several FPGAbased Web services on various hardware platforms. One of the most versatile hardware platforms we developed was described in detail in our previous publications: [1] and [2]. Each platform was equipped with a high-end Stratix-II FPGA chip and multiple blocks of synchronous dynamic random access memory (SDRAM) and was able to support built-in as well as external sensors and actuators.…”

“…First, FPGAbased Web services tend to process data locally whenever possible and transmit processing results only. For example, a smart camera, which we have previously implemented (refer to [2]), runs a motion detection or object classification service. Instead of transmitting an entire video frame, the camera sends mainly coordinates for which it detected motion or the identification number of the object recognized.…”

“…F PGA-based hardware Web services have already been implemented and described (refer to [1] and [2]). Their embedded nature allows developers to easily adapt those services to actively interact with their environment, e.g.…”
