An embedded protocol stack development platform has been unleashed for Bluetooth designs. The platform features a generic lower stack interface, documentation, and development boards. Developers can then embed their own upper layer protocol stack and applications directly onto the company's ARM7-based baseband controller. The platform includes a set of APIs and associated documentation that give access to kernel resources, GPIOs, audio controls, a UART interface, serial memory access, and other on-chip resources.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
