RISC-V Summit 2022

The RISC-V CPU and HiFi core combine to make an optimal solution. The RISC-V architecture runs the Bluetooth stack and other operating software, while the HiFi runs the audio related software. With its ability to modularize and customize for only the supported instructions, the RISC-V CPU helps optimize the cost, while the HiFi core provides the essential audio processing such as the LC3 codec and advanced features like Always On Keyword Spotting. Such flexibility offer IoT and Bluetooth applications power and cost-optimized designs. In addition, the RISC-V PMP (physical memory protection) and support for machine/supervisor/user mode makes the processor resilient to support supply chain security and protect the software IPs. Several architecture examples will be provided and discussions on their features, use cases and the design resources to bring products to the market.
