SystemC interface called ‘fcMem’ is provided, like in latest GPUs, to better exploit the AXI interface bandwidth.
Potential applications
Heterogeneous systems use advances in computing architectures to deliver improvements in power efficiency, performance, programmability and portability across computing devices. However, with heterogeneous architectures, care is required by the programmer to fully utilise hardware. Potential applications include smartphones, wearables, drones, high-end cameras, human-machine interfaces, industrial automation platforms, and security and surveillance products. The architecture has the potential to accelerate design of mobile and IoT edge devices, as it can easily handle features like voice, gesture and image recognition, haptics, graphics acceleration and signal aggregation.
