Processor provides MPEG4/H.264 over DSL solution
On Demand Microelectronics has developed a freely software programmable MPEG4/H.264 over DSL solution based on its Vector Signal Processor (VSP).
"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 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 and 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 be 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).
The central element of the platform is the VSP vector signal processor.
Patented by On Demand, the VSP is 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 datacommunications.
The novel feature of the VSP is that every customer can individually customise and create their own application-specific processor.
The basis for this is the architecture, which consists of a freely chosen number of parallel processing units, referred to as slices, which allow scalability of the processing power.
Furthermore, the core has a configurable datapath which can be 8, 16, 24 or 32bit wide.
Equipped with a state-of-the-art programming environment that can be integrated seamlessly into an already existing C++ development environment, the VSP offers designers the chance to optimise their solutions for costs, power usage and processing power in a diverse array of applications.
