2. Abstract המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 2 Creating a Smart House. A smart wireless network that can be spread out all across the house. Controlling endpoints (home appliances) or gathering data (pictures from a camera, sound from a telephone). Automatic addition of endpoints to the network. (Without the need for special configuration). Maximum flexibility when attaching to endpoints. Using the Bluetooth wireless protocol.

5. Specification המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory Hardware A printed circuit board containing a dedicated bluetooth CPU implemented on an FPGA, integrated with smart peripherals. CPU type: CISC based with special commands added for HCI support. Integrated RAM, ROM, UART for RS232, USB controller interface. Support for bluetooth radio cards of Ericsson and Philips. Software Asgard operating system is divided into two: Access point OS (automatic discovery of bluetooth endpoints, and creates a personal area network (PAN)). Endpoint OS (waits for request for connection, implements a specific application – e.g. LCD display). Both can be run on the same hardware!!! Complete development environment containing: Assembler, linker. 4
