Ceva Inc. and Ignios Ltd have unveiled a reference platform that demonstrates multiple Ceva-Teak DSP cores seamlessly operating together using SystemWeaver ' multicore-enabling SystemWeaver technology.

The demonstration platform brings together up to 16 Ceva-Teak DSP cores, with the capability for further scalability, and the SystemWeaver multicore management core in a representative SoC architecture. With the SystemWeaver approach, the software developer is presented with the same multi-threaded programming model (API) no matter how many processors are present in the SoC, considerably easing multicore software development and debug. The SystemWeaver IP core ensures that the resulting code executes efficiently on the available processing resources. This approach can be similarly utilized for Ceva-X or other homogenous or heterogeneous combinations of CEVA DSP cores.

Licensees of Ceva DSP cores and platforms who adopt SystemWeaver would benefit from the ability to easily develop and deploy multicore designs, a growing requirement for compute-intensive cellular base stations and high channel density VoIP gateways. With SystemWeaver, code can easily be developed on a single processor and then quickly retargeted to all of the devices using dynamic and flexible scheduling policies for different classes of task and processing resource.

The platform, developed in merely two weeks by Ignios using the ARM RealView Electronic System Level (ESL) tools with MaxSim technology, demonstrates the ability to easily explore and then efficiently program a multicore DSP architecture to achieve the best possible price-performance-power characteristics for an application.
