Vector processor offers versatile video solution
Embedded Award winner On Demand Microelectronics will demonstrate a fully software programmable MPEG4/H.264 over DSL solution at Electronica.
Video engine suits high-end encoders and decoders
The Sven scaleable video engine is based on the software-programmable VSP platform for high-end digital video encoders and decoders.
"The DVB solution is part of our "software defined video transceiver" product line and indicates a significant step towards our goal of providing digital video streams with one chipset for baseband and video processing of the transmission channel", explains Christian Tiringer, CEO of On Demand.
Extremely high processing power and low power usage are the outstanding features of the DVB solution, particularly as they are also the main requirements of mobile products.
The software programmability of the solution enables MPEG-2 or MPEG-4 as well as H.264 or WMV9 standards to be implemented on one and the same chipset.
At the same time the VSP takes on the entire baseband processing (such as OFDM receiver).
The complete solution follows the product philosophy of On Demand to remain fully programmable and ideal for the implementation of diverse standards such as DVB-T (terrestrial), DVB-H (handheld), DVB-S (satellite) or DVB-C (cable).
Central element of this platform is the Vector Signal Processor (VSP).
Patented by On Demand, the VSP is generally suitable for digital signal processing applications with extremely high processing power needs and low power usage, such as filter algorithms for mobile multimedia systems and broadband data communication.
The fact that every customer can individually customise and create their application-specific processor is an entirely new feature the VSP offers.
The basis for this is the architecture, which consists of a freely chosen number of parallel processing units, referred to as slices, which enable the scalability of the processing power.
Furthermore, the core is configurable in respect to the width of the datapath to 8, 16, 24 or 32bit.
Equipped with a state-of-the-art programming environment that can be integrated seamlessly into an already existing C++ development environment, the VSP offers the client the possibility to optimise the solution in regard to costs, power usage and processing power for a diverse array of applications.
