Adaptive Data Processing SoC

Overview

SFA 300 is designed to implement scalable processing applications supporting local networking. Optional accelerators and/or custom logic may be integrated to increase performance and minimise for low power.

Active power management allows for mobile and static applications. Secure dedicated subsystem for communications and data management allows for commercial, industrial, and secure applications

Benefits

SFA 300 is targeted at signal and data processing, with a medium to large performance.
Multiple SoCs may be ganged to scale performance.
Other more general applications are possible with alternate IO and compute slices. For example, IO based around the general use of PCIe & network capabilities
