Platform SoC

For a faster time to market and as a lower development cost alternative to fully customized SoC Designs, Socionext has developed platform SoC’s (PF SoC) including already the majority of typical elements being used for applications that handle documents, image-processing etc. 

Currently two different platform SoC’s are available. See below details:

Road Map

The devices shown above are just a start and more devices are under development and a future extension into the ARM v8 architecture is planned as well.

Platform SoC RoadmapPlatform SoC Roadmap

By adding customer or application specific functionality you can get your specific device. This can be achieved in different ways. The PF SoCs have a PCI Express interface which represents the easiest and lowest development cost option to configure a specific solution. By connecting user logic and the PF SoC via PCIe, users can use both, the user logic part which represents their unique advantage or functionality and a CPU with high processing performance and numerous standard interfaces. An alternative approach would be to use the USB3 port instead to connect the two devices.

Link Platform SoC to User logic via  PCI

Another possibility is to combine the platform SoC and the user logic in the same package or even on the same die.

Combine Platform SoC and user logic in one package or die

Both concepts have their specific advantages and Socionext can help making the tradeoff between functionality and performance vs. cost and schedule impact. The below graphic gives as first idea how such tradeoffs may look like. In the end the optimal solution heavily depends on the individual customer requirements.

Development Flow

An additional advantage of starting a custom SoC development based on a standard device is the availability of tooling. Socionext provides integrated development support that encompasses the whole development process from system architecture design through PCB design.

By using this service, the customer can realize not only a short design development time, but also high product quality design, minimized power consumption and low development cost.

Software

Finally, since SW has become a major part in terms of cost and development time when developing a new SoC, Socionext provides platform software to accelerate the system development. In order to improve system performance, in addition to improving hardware performance, fully drawing out the performance of SoC through software, such as middleware and drivers, is extremely important.

Socionext provides software that serves as a foundation for the PF SoC and helps to get the best possible performance. As shown below, the platform software comes with all the required hardware specific components such as drivers, Linux OS and OpenAPI, including OpenGL ES and OpenCL. Due to the SoC-dependent part being covered by the platform software, users can focus their engineering resources on developing higher level applications and concentrate on the needed additions to interface with the custom logic.
